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.

If you know the perimeter of a rectangle but don't know the length of the sides can you find the area?
no
What is the area of a rectangle with length 45 cm and width 30 cm?
we know,area of rectangle = l * b perimeter= 45*30=1350 cm ^2
How do you find the length of a rectangle if the width is 5?
You would also need to know the area of rectangle, along with the width in order to determine the length of the rectangle.
How do you know what the square feet is if 213 is the perimeter?
More information is needed. For the same perimeter, the area will vary, depending on whether you have a circle, a square, a rectangle with a ratio of 2:1, a rectangle with a ratio of 3:1, etc.
What is the perimeter of a rectangle with an area of 250 square feet and length of 25 feet?
For a start at this question, find out how wide this rectangle must be. area (250) = length (25) x width (???) The area of a rectangle is its length times its width. We should divide the area by the length (25) to get the width. The answer is 10. Then we know that each long side is 25 and each short side is 10. We know that in a rectangle, the long sides are the same length and the short sides are the same width. In order to get the perimeter, we add 25 and 25 and 10 and 10. We get 70. So the perimeter is 70.
If the area is 9 sq cm what is the perimeter?
It's undefined, because we dont know the shape of the figure. If it's a square, the perimeter is 12.. if its a rectangle the perimeter MIGHT be 20... We cant determine if we dont know the figure.
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 of a rectangle but not the length of its sides can you calculate its area?
yes
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.
Can you calculate the area if you know the perimeter?
No, you can not calculate an area if you know just the perimeter. For example, rectangle with sides of 10 and 20 would have a perimeter of 60 and an area of 200, but a square of sides 15 would have a perimeter of 60 and an area of 225. You need to know more details about the shape than just the perimeter.
How do you find the width of the rectangle?
If you know the area the divide area by length if you know perimeter subtract it by 2xlength and divide by 2
If I know the sq.ft. how do I determine the area and perimeter?
"Sq.ft." is the area. It's a phrase used by people who actually don't understandthe whole concept. If you know the sq.ft., then you know the area, because they'rethe same thing. But you can't determine the perimeter from knowing the area.
What is the perimeter of a rectangle with an area of 130 square yards?
You'd need to know one of the sides.
What is the perimeter of the rectangle with a length of 8 inches is 48 square inches?
You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.
What is the area of a rectangle with length 45 cm and width 30 cm?
we know,area of rectangle = l * b perimeter= 45*30=1350 cm ^2
How do you find the area from the perimeter of a rectangle?
If the only information that you have is ... A) the figure is a rectangle, and B) the perimeter ... then you cannot calculate the area. The area of a rectangle is the length multiplied by the height., The perimeter is twice the length plus twice the height. So, a rectangle with a length of 9 units and a height of 1 unit will have a perimeter of 20 units and an area of 9 square units. Another rectangle with a length of 6 units and a height of 4 units will also have a perimeter of 20 units, but it will have an area of 24 square units. To be able to calculate the area from the perimeter you need to know one of two additional things - either one of the measurements, or the ratio of the height to the length.+++To summarise, you can, IF you know the ratio as mentioned. Then apply that to half the perimeter to find the length and breadth.
How do you get the area of a rectangle if you know the width perimeter and length?
you times the length by the width to get the area of any rectangular or square shapes
