This is a right-angled triangle.

Calculate the area in centimetres.

Answer explanation

42mm = 4.2cm

4.2 * 5 = 21

21 * 0.5 = 10.5

This is a right-angled triangle.

Calculate the vertical height.

Answer explanation

Area = 1/2 x b x h

30 = 1/2 x 6 x h

30 = 3 x h

h = 10

This is a right-angled triangle.

Calculate the length of the base.

Answer explanation

Area = 1/2 x b x h

6.6 = 1/2 x 2.2 x b

6.6 = 1.1 x b

b = 6

Calculate the area of the triangle.

Answer explanation

Area = 1/2 x b x h

= 1/2 x 8 x 6.9

= 4 x 6.9

= 27.6
