Question

perimeter of equilateral triangle if side of triangle is 'a' cm​

Answer 1

Answer:

The perimeter of the equilateral triangle is 3a cm.

Step-by-step explanation:

The perimeter of any shape is the sum of the length of its sides.

A triangle has three sides and in an equilateral triangle, the sides are of equal length.

One side of the given  equilateral triangle is $'a'$. Thus the perimeter is,

$Perimeter = a+a+a=3a$

So the perimeter is $3a \ cm$

Answer 2

The given data in the above question,

It is given that the side of a equilateral triangle is 'a'cm.

we have to calculate the perimeter of equilateral triangle.

Thus, the formula for perimeter of equilateral triangle is as follow,

$P=3a$

Where a is the side of equilateral triangle.

Therefore,$P=3a$

Hence the perimeter of equilateral triangle is 3a.
