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.

The perimeter of a 30-60-90 triangle if the hypotenuse is 3 is: 7.098

That number is called the "perimeter" of the triangle.

49.5 units

Add the lengths of each side together to get the perimeter.

If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm

If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm

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.

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.

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.

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.

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.

An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.

The perimeter of a triangle is equal to the length of its three sides added together. If you do not know the lengths of the sides, there are many different mathematical techniques for discovering them.
