It depends on the shape. If it is a rectangle, we know that two of the sides are the same as the sides opposite them, so the missing side is the difference between half of the perimeter and the known side. If the perimeter is p, the known side is sk, and the missing side is sm,
sm = p ÷ 2 - sk = 0.5p - sk
Since the area (a) is the product of the two sides,
a = sk x (0.5p - sk) = 0.5psk - sk2
For example, if we know that the perimeter is 14 cm and one side is 5 cm, the other side is
sm = 0.5p - sk = 0.5 x 14 cm - 5 cm = 7 cm - 5 cm = 2 cm
The area is the product of the two sides, both of which we now have.
a = 5 cm x 2 cm = 10 cm2

Area of rhombus if area and perimeter is given and if you have to find altitude?
Perimeter = 4*Side so that Side = Perimeter/4 Area of a rhombus = Side * Altitude so Altitude = Area/Side = Area/(Perimeter/4) = 4*Area/Perimeter
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 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 find the area and perimeter of square?
Area = side x side; perimeter = side x 4.
What is the perimeter of a square if the area is 1M sq?
If the area is one square meter, the side length is one meter. Therefore, the perimeter is four meters.

If the area of a square is 9 square centimeters what is the perimeter of the square?
The idea is to first calculate the length of one side. Then you can multiply that by 4 to get the perimeter.
What is the perimeter of a square that has an area of 2401 cm?
As the area of a square is the length of one side squared, take the square root of 2401 to get one side's length. The perimeter is 4 times the length of one side.
How do you find the area and perimeter of square?
Area = side x side; perimeter = side x 4.
What is the area and perimeter of a rhombus?
Area equals base times height. The perimeter is 4 times the length of one side.
What is the perimeter of an area of an 40 unit square?
If 40 is the measure of one side, the perimeter is 160.
How to find the area fro the perimeter?
What is its area? Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area.
Can you find the perimeter if you know area of a rectangle?
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.
What is the perimeter of a square if the area is 1M sq?
If the area is one square meter, the side length is one meter. Therefore, the perimeter is four meters.
The perimeter of a square is 20ft whats the area?
Divide the perimeter by 4, to get the length of one side. From there, you can easily calculate the area.
