Question

The perimeter of a triangle is 141 inches. The lengths of the sides are in the ratio 5:12:13. Calculate the length of each side.

Answer 1

One side has length 5x

One side has length 12x

One side has length 13x

Explanation:

5x + 12x + 13x = 15

x = 15/(5 + 12 + 13) = 15/30 = 0.5

5(0.5) = 2.5

12(0.5) = 6

13(0.5) = 6.5
