There are at least 2 possible answers:

(1) 3 times the length of one side

(2) If for some reason you don't have the side length but just have the height then you can use the formula:

square root(H^2/.75)

Where H is the height of the triangle

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


What is the perimeter of an equilateral triangle if each side is 40centimeters?

Each side of an equilateral triangle is 9.2 ft, what is the perimeter of the triangle? Solution: 27.6 ft. The perimeter of a triangle is total length of all three sides added up. An equilateral triangle has 3 equal sides. So the perimeter is 9.2×3=27.6 ft.


The perimeter of an equilateral triangle is 63m what is the measure of one side of the triangle?

An equilateral triangle has three sides of the same length. Therefore, the length of each side of an equilateral triangle with a perimeter of 63 metres is equal to 63/3 = 21 metres.


What is the perimeter of an equilateral triangle with one side 10.5?

An equilateral triangle has all three sides the same length. → perimeter = 3 × 10.5 = 31.5 units.


What is the ratio of the length of a side of an equilateral triangle to its perimeter?

Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified. Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.


What is the perimeter for a equilateral triangle with 7.8mm sides?

Perimeter is the sum of the sides. An equilateral triangle has three sides of equal length. So the perimeter in this case would be 7.8mm x 3 = 23.4mm.


What is the perimeter of an equilateral triangle with a side of 4.3?

What is the perimeter of a triangle that has a area of 6.5 cm?

The minimum perimeter is when the triangle is an equilateral triangle. The perimeter of any other triangle with the same area will be longer. In the case of an equilateral triangle area = (√3)/4 × side² → side = √(4×6.5 cm²/√3) → perimeter = 3 × side = 3 × √(4×6.5 cm²/√3) ≈ 11.62 cm → The triangle has a perimeter greater than or equal to approx 11.62 cm.
