In an isosceles triangle, the perimeter of which is 45 cm, one of its sides is 12 cm larger than the other.

In an isosceles triangle, the perimeter of which is 45 cm, one of its sides is 12 cm larger than the other. Find the sides of the triangle.

Let’s use the conditional variable “X”, which is equal to the smaller side of the isosceles triangle.

We get an equation of the form: X + X + 12 + X + 12 = 45.

As a result of solving this equation, we have 3X = 45 – 24 or 3X = 21 or X = 21/3 = 7 centimeters.

Therefore, the sides of an isosceles triangle are 7 + 12 = 19 centimeters.

Answer: The sides of an isosceles triangle are 19, 19 and 7 centimeters.
