you multiply one of the sides by three.
The perimeter is the total length of the outside of the shape - in this case the total of the lengths of the three sides.
You'll need to know the length of one side and an angle to calculate the lengths of the others in any triangle, however in an equilateral triangle all the sides are the same length so if you know one you know them all.

How can you find sides of a triangle if one of the side and perimeter is given?
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
What is the perimeter and area of an equilateral triangle with a side of 8?
Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places
How do you calculate a side of an equilateral triangle?
Find out what 1 side is and multiply by 3 to find perimeter
How do you find the perimeter of a triangle if you know the area?
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
How long are the sides of an equilateral triangle if the perimeter is 25.2 inches?
An equilateral triangle is going to have three equal sides. The perimeter is the sum of all three sides. To find the answer, divide the Perimeter (25.2 in.) by 3 (three sides) 25.2 in. / 3 = 8.4 in.
