Question

what is perimeter of a triangle

Answer 1

perimeter of a triangle refers to the sum of the lengths of all three sides

for an equilateral triangle - 3(side)

for an isosceles triangle - base + 2 (side which have equal length)

for scalene triangle - sum of all 3 sides

Answer 2

First let's know what is perimeter?

A perimeter is the sum of length of boundaries of a closed figure.

So perimeter of a triangle = Side1 + side2 + side3

If the triangle is equilateral then all sides are equal then perimeter = 3 × side

If it is an Isoceles Triangle, then two sides are equal then perimeter = 2 × equal side + unequal side

For scalene triangle, perimeter becomes Sum of all sides.
