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.
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
-- 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] .
divide the perimeter by four to get the length of one side then square your answer to find the area
Take the measurement of one side of the square and multiply it by 4.
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.
There is only one equilateral triangle with a perimeter of 60 units. Its side lengths are integers.
Divide the perimeter by eight.
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
-- 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.
Perimeter = 8 x (length of one side)
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.
You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.
-- 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] .
divide the perimeter by four to get the length of one side then square your answer to find the area
Take the measurement of one side of the square and multiply it by 4.
There are many formulas for perimeter depending on what shape you are trying to find the perimeter of. The perimeter is the distance around a shape, so one formula to find perimeter is simply adding all the side lengths together.
One side will be 28/4 = 7m
