Answer:

The sides of the triangle are 7.

Step-by-step explanation:

The formula to compute the perimeter of a triangle is:

P=a+b+c

Here a, b and c are the sides of the triangle.

An equilateral triangle has all sides equal.

Given, the perimeter of an equilateral triangle is 21.

Compute the measure of the sides as follows:

P=a+b+c\\21=a+a+a\\3a=21\\a=7

Thus, the sides of the triangle are 7.
