In an isosceles triangle, the base is 3 times less than the lateral side and the perimeter is 70cm

In an isosceles triangle, the base is 3 times less than the lateral side and the perimeter is 70cm, calculate the lengths of the sides of the triangle.

To solve this problem, it is necessary to recall the definitions of an isosceles triangle.

An isosceles triangle is a triangle whose two sides are equal.

You can solve the problem using an equation.

X is the base of the triangle.

3 * X – side of the triangle.

Let’s make an equation.

X + 3 * X + 3 * X = 70.

7 * X = 70.

X = 10 cm base of the triangle.

3 * X = 3 * 10 = 30 cm side of the triangle.

Answer: the two sides of the triangle are 30 cm and the base is 10 cm.
