Answer 2

Given :-

Two sides of a triangle each = 25 cm

Third side of the triangle = 36 cm

To Find :-

The perimeter of the triangle.

Analysis :-

From the question, we understand that the triangle is isosceles.

Substitute the values accordingly in it's respective formula.

Then you can easily find the perimeter.

Solution :-

From the question, we understand that the triangle is isosceles.

By the formula,

$\underline{\boxed{\sf Perimeter \ of \ a \ triangle=a+b+c}}$

Given that,

Angles one and two are equal = 25 cm

Third angle = 35 cm

Substituting their values,

Perimeter = 25 + 25 + 35

Perimeter = 85 cm

Therefore, the perimeter of the triangle is 85 cm.
