A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 19 feet more than the length of the shortest side. Find the dimensions if the perimeter is 143 feet.

shortest side  x
2nd side  2x
3rd side  x+19
solve for x, the sub into my definitions
x + 2x + x+19 = 143
