Let the length of the base of the triangle be 3 * X cm, then the length of the side of the triangle is 4 * X.

The perimeter of the triangle is: P = 3 * X + 4 * X + 4 * X = 33 cm.

11 * X = 33 cm.

X = 33/11 = 3.

Then AC = 3 * 3 = 9 cm.

BC = ВA = 4 * 3 = 12 cm.

Answer: The sides of the triangle are 9 cm, 12 cm, 12 cm.
