a flower bed is the shape of a triangle with one side twice the length of the shortest side and the third side is 30 ft more than the shortest side. find the dimentions if the perimeter is 102 ft.

x = shortest side
2x = 2nd side
x + 30 = 3rd side
x + 2x + x + 30 = 102
Solve for x, and use to determine the dimensions as defined above
