A flower-bed is in the shape of a triangle with one side twice the length of the shortest side and the third side 15 feet longer than the shortest side. If the perimeter is 100 feet and if x represents the length of the shortest side, find an equation to solve for the lengths of the three sides.

Let x, 2x, x+15 be the sides of the triangle

P = x + 2x + x + 15 = 100
4x = 85

then just solve for x, 2x, and x + 15
