Question

The lengths of the sides of a triangle are in the extended ratio 6 ​: 7 ​: 9. The perimeter of the triangle is 44 cm. What are the lengths of the​ sides?

Answer 1

Add 6+7+9, which gives 22.

Divide 44 by 22, which is 2.

Multiply the ratio by 2:

(6 : 7 : 9) * 2 = 12 : 14 : 18

The lengths of the sides are 12cm, 14cm, 18cm.
