As part of your work on shapes in KS3 Maths, you'll be very familiar with both perimeter and area. The perimeter is the total distance around the outside of a two-dimensional shape. The area is the amount of space covered by the shape's surface. To work out the area of a rectangle multiply the length of its longest side by the length of its shortest side. To work out its perimeter just add together the length of all of its sides.
So, you are fine with squares and oblongs. You might also be confident with triangles. But can you work out the perimeter and area of shapes such as a trapezium and a rhombus? They have their own rules which it will do you good to learn. The following quiz provides a more advanced look at calculating areas and perimeters of 2-Dimensional shapes.
Before trying this quiz, you might want to refresh your memory by playing the easier quiz called 'Level 3-4 Perimeter and Area 01'. Or, if you are already quite confident, then jump right on in. Good luck!
