Question

For an isosceles triangle having base b and each of equal side a find the perimeter

Answer 1

2a+b; a =equal sides
b=base
In triangle,there are two equal sides i.e ,a then p=2a+b

Answer 2

Answer:

Perimeter, P = a +2 b

Explanation:

The closed figure that is made up of three sides is called a triangle. The triangle can be of many types i.e. isosceles, scalene and equilateral.

We know that in an isosceles triangle the two sides of a triangle are same while one side is different.

Let the base of an isosceles triangle is b and other two sides are a. The perimeter of any figure is defined as the sum of all the sides.

So, the perimeter of an isosceles triangle is equal to :

$P=a+b+b$

$P=a+2b$

Hence, the perimeter of an isosceles triangle is a +2b. Hence, this is the required solution.
