As part of your work on shapes in KS3 Maths, you will need to know about perimeter and area. The perimeter is the total length of a shape's sides. The area is the size of a shape's surface.
There are formulae for working out perimeters and areas. Taking a square as a simple example, its perimeter is its length x 4 and its area is its length x its width. The area of a three-dimensional shape is worked out by adding the area of each of its faces together. So, for a cube, work out the area of one of its square faces and then multiply the answer by 6.
This quiz is all about the perimeter and area of 2D shapes; mainly shapes such as squares and rectangles. This will give you some easy practise in calculating perimeters and areas. You might then like to try our more advanced quiz called 'Level 5-6 Perimeter and Area 02'.
