Perimeter of Triangle = a + b + c
so if you have an equilateral with say 4 cm sides you would add
4+4+4=12cm
Just add up its 3 equal sides

Find the area of an equilateral triangle if its perimeter is 18 ft
The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, as all three sides of an equilateral triangle are equal in length. Therefore, if the length of one side of the equilateral triangle is represented by "s," the perimeter would be 3s. This is because there are three sides in total that need to be added together to find the perimeter of the equilateral triangle.

Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
An equilateral triangle has three sides of exactly the same length. Therefore, if one side of the triangle is equal to 12 yards, then the perimeter of the triangle is equal to 12 x 3 = 36 yards.
