The perimeter of a shape is the sum of its side lengths. It is important to label all side lengths so you don't miss any out.
![perimeter problem solving ks3 Illustrative background for Example 1](https://image-v2.cdn.app.senecalearning.com/2018-08/0f9b5378-0692-4e8d-a104-27e5aaa55df2/Perimeter%201,h_400,q_80,w_640.jpg)
- To find the perimeter of this shape, we need to add all the side lengths together.

Missing length
- Sometimes you might need to work out the missing length of a shape in order to find the perimeter.
- What is the perimeter of the rectangle above?

Printable Area and Perimeter Worksheets With Answers
Why is learning about area and perimeter important.
Calculating perimeters and areas is an important skill which is used by many people in their everyday lives.
Architects, engineers and construction workers will need precise measurements of area and perimeter in order to construct a building to the right specification. It is not just professionals that need a solid knowledge of area and perimeter; knowing the area of a room can help work out how much paint or flooring is needed to fill the space when redecorating.
Improve Students’ Problem Solving Skills
Regularly practicing area and perimeter questions with children can help them develop good problem solving and logic skills.
The importance of these skills should not be underestimated, as these skills are useful for their learning in other subjects, as well as preparing them for the workplace.
Worksheets Make Learning Area and Perimeter Enjoyable
Children start learning about perimeters and areas in KS2, so it is important to use area and perimeter materials which make the topic easy to understand and enjoyable for them.
Worksheets with fun activities help children learn about this important area of maths. Using good quality resources throughout their education will prepare children for more advanced area and perimeter questions, such as calculating areas of compound shapes and areas of sectors.

Area and Perimeter
The area of a shape is the space inside the shape. Area is measured in squares.
Finding the area of a rectangle
Here is a rectangle drawn on a centimetre grid.
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-1.jpg)
To find the area of a rectangle multiply the length by the width. (We could also count the squares but this will not work from more complex questions)
In this example we have a length of 6cm and a width of 3cm.
Area = length × width Area = 6 × 3 Area = 18 cm 2
The units are cm 2 : one cm 2 is a square that measures 1cm by 1 cm.
Example 1: A rectangle is drawn on a centimetre grid Calculate the area of the rectangle
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-2.jpg)
Area = length × width Area = 5 × 4 Area = 20cm 2
A rectangle is drawn on a centimetre grid. Calculate the area of the rectangle.
Finding the area of a triangle
We can think of a triangle as half of a rectangle
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-9.jpg)
To calculate the area of a triangle we can half the area of a triangle
The area of a triangle = 1 ⁄ 2 × base × height
Example 2: Here is a triangle drawn on a centimetre grid. Calculate the area of the triangle.
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-10.jpg)
Area = 1 ⁄ 2 × base × height Area = 1 ⁄ 2 × 4 × 6 Area = 2 × 6 Area = 12cm 2
Example 3: Calculate the area of the triangle.
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-11.jpg)
For the area calculation we use the perpendicular height (it must be straight up, not diagonal). The height of this triangle is 12 metres.
Area = 1 ⁄ 2 × base × height Area = 1 ⁄ 2 × 8 × 12 Area = 4 × 12 Area = 48m 2
A triangle is drawn on a centimetre grid. Calculate the area of the triangle.
Calculate the area of the triangle.
Finding the area of a parallelogram
A parallelogram is a quadrilateral with two sets of parallel sides.
A parallelogram can be made into a rectangle by cutting off and moving a triangle:
The area of a parallelogram = base × height
Example 4: Here is a parallelogram drawn on a centimetre grid. Calculate the area of the parallelogram.
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-20.jpg)
Area = base × height Area = 4 × 3 Area = 12cm 2
Example 5: Calculate the area of the parallelogram.
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-43.jpg)
For the area calculation we use the perpendicular height (it must be straight up, not diagonal). The height of this parallelogram is 11 metres.
Area = base × height Area = 8 × 11 Area = 88m 2
A parallelogram is drawn on a centimetre grid. Calculate the area of the parallelogram.
Calculate the area of the parallelogram.
Finding the area of a trapezium
The image below shows a trapezium, a trapezium (trapezoid in American English) is a quadrilateral with two parallel sides.
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-53.jpg)
The area of a trapezium = 1 ⁄ 2 (a + b) × height Where a and b are the lengths of the two parallel sides
This formula can be made by splitting the trapezium into a rectangle and a triangle (you don't have to know where the formula comes from, you just have to know the formula).
Example 6: Find the area of the trapezium
For the trapezium above: Area = 1 ⁄ 2 (6 + 10) × 7 Area = 1 ⁄ 2 (16) × 7 Area = 8 × 7 Area = 56 cm 2
A trapezium is drawn on a centimetre grid. Calculate the area of the trapezium.
Calculate the area of the trapezium.
The perimeter of a shape is the distance around the edge of the shape
To find the perimeter of a shape we add up the lengths of all of the sides
This rectangle has two sides with a length of 6cm and two sides with a length of 3cm
Perimeter = 6 + 6 + 3 + 3
Perimeter = 18 cm
Example 1: A rectangle is drawn on a centimetre grid Calculate the perimeter of the rectangle
Perimeter = 5 + 5 + 4 + 4 Perimeter = 18cm
Example 2: Calculate the perimeter of the triangle
![perimeter problem solving ks3 perimeter problem solving ks3](https://www.mathsgenie.co.uk/images/area-and-perimeter-52.jpg)
Perimeter = 10 + 9 + 7 Perimeter = 26m
A rectangle is drawn on a centimetre grid. Calculate the perimeter of the rectangle.
Calculate the perimeter of the rectangle.
