The perimeter of the isosceles three squares is 26cm, and the base is 8cm. Find the side?

An isosceles triangle is a triangle whose two sides and angles at these sides are equal, and the third side is called the base. Let’s denote the side by “x”. Knowing that the perimeter of the triangle is 26 cm, and the base is 8 cm, we make an equation and find the value of the variable “x”.

x + x + 8 = 26;

Let’s add similar monomials on the left side of the equation.

2x + 8 = 26;

Move the positive number 8 to the right side of the equation by changing the sign of the number to negative.

2x = 26 – 8;

Find the value of the difference on the right side of the equation.

2x = 18;

We perform division of the product equal to 18 by the second factor of 2.

x = 18/2;

x = 9 cm.

Answer: 9 centimeters.
