John used 3 rubber bands to form the sides of triangle ABC where AB = 8 cm, BC = x cm and AC = 2x cm. Bob stretches two of the elastic bands and enlarges triangle ABC. The sides BC and AC are stretched to 2 times its original length. What is the perimeter of the stretched triangle ABC?
Level 2
The sides of a triangle are in the ratio 5 : 2 : 3. The length of the longest side is 20 cm. Find the length of the shortest side of the triangle.
