Find the perimeter of an isosceles triangle is 29.6 cm.If the base is 6 dm, then find its side

It is known from the condition that the perimeter of an isosceles triangle is 29.6 dm. If the base is 6 inches, then find its side.

Let’s remember the definition of an isosceles triangle.

An isosceles triangle is a triangle that has two sides of the same length.

So the perimeter, which is the sum of the lengths of all sides, for an isosceles triangle can be written as follows:

P = a + 2b;

Substitute and solve the resulting equation:

6 + 2b = 29.6;

2b = 29.6 – 6;

2b = 23.6;

b = 11.8 in. side length.
