Question

One side of the triangle is 5 meters longer than the second side. The third side is four times. If the perimeter of the triangle is 65 meters, how long is the second side

Answer 1

Answer - 10 meters

10 meters

Explanation:

Using the ratios given, we have the three sides in terms of one side.

(x, x+5, 4x)

The perimeter is the sum of all of them:

65 = x+x+5+4x ; 65 = 6x+5

6x = 60 ; x = 10

x+5 = 15

4x = 40
