Question

The sides of a triangle are in the extended ratio 2:5:7. If the perimeter of the triangle is 45 inches, then what is the length of the shortest side?

Answer 1

Total ratio units = 2 + 5 + 7 = 14

Value of one ratio = 45/14 = 3.21 in

Now, sides = 2(3.214) = 6.43
= 5(3.214) = 16.07
= 7(3.214) = 22.5

In short, Your Sides would be: 6.43, 16.07 & 22.5 in

Hope this helps!
