How do you find the length and wide of an area if you know the perimeter and an area?
Perimeter = 2*L + 2*W
Area = L*W
L = Area / W
Perimeter = 2*Area / W + 2*W
W * Perimeter = 2*Area + 2*W^2
Let A=area, and P= perimeter.
0=2W^2-PW+2A
W= (P + root(P^2-16A))/4
or
W= (P - root(P^2-16A))/4
Once you have W,
L is simply A/W.
Have fun, and maybe include some numbers to work with next time.

You have to add up all the sides of the shape.
How do you find the perimeter of a rectangle with only the width or length and the area given?
It not possible you nit witt that is not true length x width = area If you know length and area, solve width width = area / length then 2 x length + 2 x width = perimeter
What measurements do you need to find the area and perimeter of a square?
You only need to know the length of one side. Knowing the side length (s) you can find the area (multiply s by s) and perimeter (multiply s by 4)
How do you find the perimeter when you know the area?
There is no possible way to. You can only add up all the sides to get the perimeter.---It is not impossible. You can get the perimeter from area very easily.First, you find the square root of the area, which will be the length of each side (assuming it is a square).Then, once you've found the length of each side, you multiply it by 4, and you should have the perimeter.

Can you find the perimeter and length if you know the area and width?
no
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.
If you know a perimeter of a square but not the length or width how do you find the area?
Divide the perimeter by 4 and then square the result to find the area of the square.
If you know the perimeter of a rectangle but don't know the length of the sides can you find the area?
no
If you know the perimeter how do you find the area?
Perimeter equals to 2 times the length plus 2 times the breadth. Area equals to length multiply by breadth

The perimeter of a rectangle is 72m the width of the rectangle is 16m what is the area of the rectangle?
To find the area of a rectangle, you need to know the formula: Area = length x width. Given that the perimeter is 72m and the width is 16m, we can calculate the length by using the formula for perimeter of a rectangle: Perimeter = 2(length + width). Substituting the values we have, 72 = 2(length + 16), which simplifies to length + 16 = 36. Therefore, the length of the rectangle is 20m. Finally, the area of the rectangle is 20m x 16m = 320 square meters.
