The perimeter of a shape is the distance all the way around it.
The perimeter doesn't have sides.
If it's a right triangle, you use the Pythagorean theorem: a2 + b2 = c2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides. Also, if angle A is the angle opposite side a and angle B is the angle opposite side b, sin A = cos B = a ÷ c, sin B = cos A = b ÷ c, tan A = a ÷ b, and tan B = b ÷ a. With these equations you should be able to calculate the length of any side of a right triangle given either the lengths of the other two sides or given the length of one side and the magnitude of angle A or angle B.

What is the perimeter of an equilateral triangle that measures 15 feet on one side?
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
How do you find the perimeter of a square if you have its area?
-- The perimeter of the square is [4 times the length of one side] . -- The length of one side of the square is [square root of its area] .
How do you get area of a square with perimeter?
divide the perimeter by four to get the length of one side then square your answer to find the area
How you can use multiplication to find the perimeter of a square?
Take the measurement of one side of the square and multiply it by 4.
How can you find sides of a triangle if one of the side and perimeter is given?
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.
