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 do you find perimeter of a triangle with 1 measurement?
If the triangle is equilateral, you don't have a problem, but if not you have to measure the sides.
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.
What is the area of an equilateral triangle that has a perimeter of 71 feet?
Find the area of an equilateral triangle if its perimeter is 18 ft
The altitude of an equilateral triangle is 8.3m. find the perimeter?
28.75m
How do you find the length of a triangle when perimeter is given?
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
Find the area of an equilateral triangle that has a perimeter of 21 inches Round the answer to one decimal place?
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
How do you find perimeter of a triangle with 1 measurement?
If the triangle is equilateral, you don't have a problem, but if not you have to measure the sides.
What is the perimeter of an equilateral triangle with an altitude of 15?
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
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.

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 an equilateral triangle?
Perimeter of Triangle = a + b + cso if you have an equilateral with say 4 cm sides you would add4+4+4=12cmJust add up its 3 equal sides
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.
