Question

One side of a triangle is two times the second side. The third side is 5 feet longer than the second side. The perimeter of a triangle is 49 feet. Find the length of each side.

Answer 1

Second side= x
First side = 2x
Third side = x+5
x+2x+x+5=49
4x=44
x=11

1st side= 22
2nd side = 11
3rd side = 16
