Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
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.
It depends on what is known about the triangle.

The perimeter of the equilateral triangle is 3 times 4 = 12 cm
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
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.
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
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.
Lengths of: equal side+equal side+base = perimeter
That number is called the "perimeter" of the triangle.
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
Let x be the side of the triangle. Thus 4(x-5) is the perimeter of the square.Balance by the perimeter relation,3x = 7+4(x-5)Solve for x,x = 13 inches
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
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.
It depends on what is known about the triangle.
