Asked by Valdo

The longest side of a triangle is six more units that the shortest side. The third side is twice the length of the shortest side. If the perimeter of the triangle is 25 units, write and solve an equation to find the length of all three sides of the triangle.

Let s = shortest side, then longest = s+6 and 2s = third side.

s + (s+6) + 2s = 25

Solve for s then the others.
