Question

find the perimeter of an equilateral triangle whose each side is Y.

Answer 1

side=y

•therefore., all the sides are equal in a equilateral triangle.

•perimeter of a equilateral triangle =3y cm/m
perimeter is boundary.
so, we can add all the 3 sides.

Answer 2

Side 1- y
Side 2- y
Side 3- y

Finding the perimeter means finding the area of the boundary of a figure, in case of triangle we add all the three sides in an order to find the perimeter.

Thus the perimeter of the equilateral triangle would be (y+y+y)cm.
= 3y cms.(Ans)
