The perimeter of the triangle is 37 meters. The second side is one-half of the first side in length. The third side is 3 meters less than the first side. Find the length in meters of each side of the triangular region.
.
Let x = length of 1st side
x/2 = length of 2nd side
x-3 = length of 3rd side
.
The sum of the sides = perimeter
.
x + x/2 + (x-3) = 37
2x + x/2 = 40
4x + x = 80
5x = 80
x = 16 meters(1st side)
x/2 = 8 meters (2nd side)
x-3 = 15 meters (3rd side)
