The MNL triangle is isosceles. The perimeter of the triangle is 60 cm, and the MN side is 2 times

The MNL triangle is isosceles. The perimeter of the triangle is 60 cm, and the MN side is 2 times as long as the ML side. Find the length of the sides of the triangle.

We draw up an equation in which the value of the side ML is taken as x cm.

Since the length of the side MN is 2 times longer, it will be equal to: 2 * x cm.

We know that this triangle is isosceles, so its perimeter will be:

x + 2 * x + 2 * x = 60.

5 * x = 60.

x = 60/5 = 12 cm (the length of the base of the triangle).

2 * x = 2 * 12 = 24 cm (the length of the side of the triangle).

Answer:

The length of the sides of the triangle is 12, 24 and 24 cm.
