One side of a triangle is 5 meters longer than the second side. The third side is four times the length of the second side. If the perimeter of the triangle is 65 meters. How long is the second side?
let the length of the second side be x
the first side will be x+5
The third side will be 4x
4x+x+5+x=65
6x+5=65
6x=60
x=10 meters whch is the second side
