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?

Hi there,

5=5x4=20
7=7x4=28
10=10x4=40

this is how u get ur answers

Hope this helps best of luck my friend :3

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.
