The base of the exactly femoral triangle is 3 times smaller than the lateral side. And its perimeter is 28 cm.

The base of the exactly femoral triangle is 3 times smaller than the lateral side. And its perimeter is 28 cm. Determine the sides of the triangle.

Let the base of this isosceles triangle be x, then its two sides are equal to 3 * x. Knowing that the perimeter of the triangle is 28 cm, we can write the equation:

3 * x + 3 * x + x = 28;

7 * x = 28;

x = 28/7 = 4.

Therefore, the base of the triangle is 4 cm, and its sides are 3 * 4 = 12 cm.
