Let us consider a triangle ABC which is isosceles in shape that is two of its sides are equal in length. Let AB = AC = x and BC = y. In other words, we can say that the perimeter of an isosceles triangle is the sum of twice the length of the equal sides and the third side.

Answer 2

Answer:

The length of the two equal side is 5 cm.

We know,

The formula to calculate the perimeter of an isosceles Triangle is P = 2a + b unit .

Therefore ,
