In an isosceles triangle with a 56cm perimeter, the base is 2: 3 to the side. Find the sides of the triangle.

1. Let’s say one part in relation to the sides of the triangle is x centimeters.

2. The base is x * 2 = 2x centimeters.

3. Lateral side x * 3 = 3x centimeters.

4. Let’s make an equation.

2x + 3x * 2 = 56;

8x = 56;

x = 56/8 = 7;

x = 7;

Answer: One side x * 2 = 7 * 2 = 14 centimeters. The other two are x * 3 = 7 * 3 = 21 centimeters.
