Question

The lengths of the sides of a triangle are in the extended ratio 5 ​: 7 ​: 10. The perimeter of the triangle is 88cm. What are the lengths of the​ sides?

Answer 1

So you know that altogether the ratio adds up to 22. just do 88/22 to find what 1 is. then just multiply  88/22=4
5=5x4 which is 20
7=7x4  which is 28
10=10x4 which is 40            the answer is 20 cm, 28 cm, and 40 cm.
