One side of a triangle is 2 times the second side. The third side is 5 feet longer than the second side. The perimeter of a triangle is 81 feet. Find the length of each side.

The length of the side of the triangles are;

First side = 38 ft

Second side = 19 ft

Third side = 24 ft

Step-by-step explanation:

To solve the question we are going to take;

Second side is x ft

Since, the first side is 2 times the second side then;

First side of the triangle is 2x ft

Since the third side is 5 ft less than the second side, then;

The third side is (x+5) ft

But, the perimeter of the triangle is 81 ft

Perimeter of a triangle is given by the sum of sides;

Therefore;

x + 2x + (x + 5) = 81 ft

4x + 5 = 81

4x = 76

x = 19 ft

Therefore;

Second side = 19 ft

First side = 38 ft

Third side = 24 ft
