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 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.


What is the perimeter of 36cm2?

The perimeter cannot be directly calculated from the area alone, as it depends on the shape of the figure. For example, a square with an area of 36 cm² would have a perimeter of 24 cm, while a rectangle with the same area could have a different perimeter. To determine the perimeter, you need to know the specific dimensions or shape.


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


How do you find the width of a rectangle if you know the length?

To find the width of a rectangle when you know the length, you can use the formula for the area of the rectangle, which is Area = Length × Width. If you have the area, you can rearrange the formula to solve for width: Width = Area ÷ Length. If you don't have the area, you will need additional information, such as the perimeter or the relationship between length and width, to determine the width.


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


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.


What is the perimeter of a rectangle with an area of 130 square yards?

You'd need to know one of the sides.


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 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.
