how do you work out the Area of a rectangle?

• height x width

• diagonal length

• Height x depth x width

• width x diagonal

What do the internal angles of a triangle equal?

• 180

• 90

• 260

• 360

 $area=\frac{1}{2}base\ x\ height=\frac{^{base\ x\ height}}{2}$  work out area is base is 15cm and height is 10cm

The circumference is ...

• the distance around a full circle

• the length across the centre of a circle

• 1/2 the length across a circle

The Diameter of a circle is

• the distance from the centre to the outer edge

• the furthest distance across the centre

• the distance around the outside

• the volume

how do you work out the volume of a cuboid

• Height x Width x Depth

• Depth x Height x Area

• Area x 10

• Length squared
