Answer 2

Perimeter of an Isosceles Triangle

To find the perimeter of an isosceles triangle, we need to know the length of the base and the length of the two congruent sides. In this case, we are given that the base of the triangle is 35 cm and one of the congruent sides is 26 cm.

The perimeter of a triangle is the sum of the lengths of all its sides. In an isosceles triangle, two sides are equal in length, so we can calculate the perimeter by adding the lengths of the base and the two congruent sides.

Let's calculate the perimeter:

Perimeter = Base + Side1 + Side2

Given: Base = 35 cm Side1 = Side2 = 26 cm

Perimeter = 35 cm + 26 cm + 26 cm

Calculating the sum:

Perimeter = 35 cm + 26 cm + 26 cm = 87 cm

Therefore, the perimeter of the given isosceles triangle is 87 cm.
