Let x be the length of the shortest side.

Then the lengths of the other two sides are x + 4 and 2x.

The perimeter of the triangle is x + (x + 4) + 2x.

As the perimeter is 40, we have

x + (x + 4) + 2x = 40

Solving for x, we have

x+ x + 4 + 2x = 40

4x + 4 = 40

4x = 36

x = 9

So the length of the shortest side is 9 cm.

The lengths of the other two sides are:

x + 4 = 9 + 4 = 13 cm

2x = 2*9 = 18 cm
