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 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 is the sum of all sides. An equilateral triangle has three sides of equal length. So if one side is 5 inches, and we have three of these, we get a perimeter of 15 inches.
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.
