………………………………………………………………………………………………………………………………………………………………..

Apply what you have revised about perimeter, area and volume.

Remember

It is important that you remember the formulae for calculating the area of different shapes:

Rectangle and parallelogram = base x perpendicular height

Triangle = (base x perpendicular height) ÷ 2 – it is a very common error to forget to half this!

Circles: area = πr2 and circumference = πd – don’t muddle up the radius and diameter – the

diameter is the long one as it is the longer word!

Trapezium = 1/2 (top + bottom) × height

Don’t forget your units and whether they are squared (area) or cubed (volume)

For composite shapes, split them up on the drawing and check your lengths very carefully.

For surface area write out the area of each face first before adding them all together – check you have all of the sides.

1. The diagram shows the plan of a rectangular garden with two circular flower beds.Apart from the flower beds, the rest of the garden is covered in grass. Estimate thearea of the grass.
