To find area given perimeter, rename perimeter to circumference and solve with these formulas:
Circumference = 2πr (or 2 * π * r)
Area = πr^2 (or π * r * r)
With these the area can be found from circumference(or perimeter) as follows:
A = π(C / 2π)^2
Now, to find the perimeter given the area;
We use A = πr^2 and rearrange then solve:
r = √(A / π)
So, the circumference would be 2πr = 2π√(A / π)
if it is a triangle it is 1/2 times the length of the base times the length of the height, if it is a square or rectangle it is the length times the width, if it is a circle it is pi times the radius squared
==========================
In other words . . . You can'tdetermine the area from knowledge of the perimeter.
You need more information in addition to the perimeter. You also need to be told the
shape, and if it's not a circle, then you need to be given at least one dimension.
If given only the perimeter, then there are an infinite number of shapes that could
have that same perimeter, and for any shape that's not a circle, there are an infinite
number of that shape that could have the same perimeter.

How do you determine the area and perimeter of a rectangle?
for area we should multiple length X breadth for perimeter we should do 2x(LxB)
How do you determine the area of a rectangle if you know the perimeter?
You can't. The perimeter doesn't tell the area. There are an infinite number of shapes with different dimensions and different areas that all have the same perimeter.
How do you get the dimensions of rectangular lot given the perimeter and area?
By halving its perimeter and using the quadratic equation formula.
What is the perimeter of 8276.4 square feet?
There is not a single perimeter associated to a given area. You can have different perimeters, depending on the shape.
Find the area and perimeter of a given circle?
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
What is the perimeter of a room that is 246 square feet in area?
Based on the given information, there is no way to determine the perimeter.
How do you determine area if perimeter is given?
More information is required in order to answer this question. What is the shape for which the perimeter is given? If it anything other than a circle or regular polygon it is not possible to determine the area. For a circle or regular polygon, the answer will depend on the shape.
How do you determine area when perimeter and length of a square is given?
The perimeter of square is 4 x length If you have perimeter only divide by 4 to get length and The area of square is length x length If you already have length that is all you need to know
How do you find the perimeter using area?
Depending on the figure given you can find the area from the perimeter For example- If you have a square with a perimeter of 24, you divide 24 by 4 because all the sides of a square are congruent. In turn you will 6 as each side of the square The formula for the area of a square is side2 so you get 62 which is 36. The area is 36
How do you find area when given perimeter and width?
If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)
How do you find the perimeter of a hexagon if the area is given?
In general you cannot find the perimeter of any shape if only the area is given.
What is the shape for a figure to have a perimeter of 20 and an area of 18?
Perimeter and area are not sufficient to determine the shape of a figure.
What is the perimeter of a square when given the area 121?
The perimeter is 44 units.
How do you calculate perimeter of a square when its area is given?
Perimeter = 4 times the square root of the area.
What would the perimeter be of a room with area of 246 square feet?
Based on the given information, there is no way to determine the perimeter. Assuming the room is a square, then you could take the square root of 246 (≈15.6843871) and multiply that by 4 (≈ 62.7375484), which would be the perimeter of a square room with this area.
What are the dimesions of a parallelogram that has an area of 24 cm and a perimeter of 22cm?
The area and perimeter of a parallelogram are not sufficient to determine its dimensions.
What is the Area and perimeter of Wisconsin?
The area of Wisconsin is 65,503 square miles. The perimeter of Wisconsin is 1379 miles. The length or width plus the area are used to determine the perimeter.
