A compound shape is a shape created using two or more basic shapes.

A composite shape is an alternative for a compound shape.

The area is the size of the surface and states the number of unit squares needed to completely cover that surface.

Maths

In this unit, pupils built upon their prior learning of the area of different shapes. In the future unit, pupils will continue to further develop their understanding of shapes by considering surface area and volume of pyramids, spheres and cones.

In the prior unit, pupils derived the formula for the circumference and area of a circle. In this unit, this knowledge is combined with knowledge of fractions to find the arc length and area of a sector.

2D and 3D shape: compound shapes

To find the area of this compound shape, the most efficient method would be __________.

The area of this compound shape is {{ }} cm² to the nearest square centimetre.

The area of this compound shape is {{ }} cm² to 1 decimal place.

A rectangle is inscribed in a circle. Match each measurement to its value.

The area of the circle, to 1 decimal place, is {{}}cm².

A sector is the region formed between two radii and their connecting __________.

The area of this semicircle is __________.

The area of this shape is equal to {{ }} the area of a semicircle with the same diameter. 

The area of this sector is {{ }}$$\pi$$ cm².
