Question

The lengths of the sides of a triangle are in the extended ratio 5:7:10. The perimeter of the triangle is 44 cm. What are the lengths of the sides?

Answer 1

10 cm, 14 cm, 20 cm

Explanation:

The sum of the ratio units is 5+7+10 = 22, so each unit stands for 44 cm/22 = 2 cm.

The side lengths are the ratio values multiplied by 2 cm:

10 cm : 14 cm : 20 cm
