We know that in equilateral triangle all three sides are equal in length.

The perimeter of equilateral triangle18, which means the sum of all three sides will be equal to 18

x+x+x=18

3x=18

x=6

Thus, the sides of triangle are

6,6,6

Step 2. Concept used.

Area of an equilateral triangle can be found using the formula

A=34a2

Where,

a=The sides of triangle.
