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.
Measure it or use trigonometry if the 'included' angle is given.
Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.
The isosceles triangle has a perimeter of: 14+14+9 = 37 feet
The perimeter would be 18 cm.

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

If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.

The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, as all three sides of an equilateral triangle are equal in length. Therefore, if the length of one side of the equilateral triangle is represented by "s," the perimeter would be 3s. This is because there are three sides in total that need to be added together to find the perimeter of the equilateral triangle.
The perimeter would be 18 cm.
Perimeter = 3*8 = 24 feet
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
The perimeter of an equilateral triangle with a side length of 4 inches is 12 inches. Each side of an equilateral triangle is equal in length, so the perimeter is found by multiplying the side length (4 inches) by 3.
