The dimensions of the triangle are 27 feet, 54 feet and 56 feet.
Let the shortest side be x.
One side is twice the length of the shortest side. This will be 2x.
The third side is 29 feet more than the length of the shortest side. This will be x + 29.
The perimeter will be illustrated as:
x + 2x + x + 29 = 137
4x = 137 - 29
Divide
4x = 108
x = 108/4.
x = 27 feet
Second side = 2x = 2 × 27 = 54 feet
Third side = x + 29 = 27 + 29 = 56 feet
