Question

The perimeter of a triangle is34 ft. One side of the triangle is 2 times the second side. The third side is 6 ft longer than the second side. Find the length of each side

Answer 1

Let the second side = x

The first side is 2x ( 2 times the second side)

The third side is x + 6 ( 6 feet longer than the second side)

Now you have: x + 2x + x + 6 = 34

Simplify to get:

4x + 6 = 34

Subtract 6 from both sides

4x = 28

Divide both sides by 4:

X = 7

1st side = 2x = 2*7 = 14 feet

2nd side = x = 7 feet

3rd side = x + 6 = 7 + 6 = 13 feet
