You can't.
If you know the area of a rectangle, that's not enough information to find the perimeter.
If you know something else, such as the relative lengths of the sides, you could solve this with an equation. For example:
A rectangle has an area of 72in2, and the length is 14in greater than the width. What is the perimeter of the rectangle?
Let w inches be the width of the rectangle. Then the length will be w+14 inches.
Area = length x width = (w+14)w = w2 +14w = 72.
Whoops, we have a quadratic equation, w2+14w -72 = 0. This can be solved by factoring: (w+18)(w-4) = 0 -> w = -18 or w = 4. It can't be negative, so the width must be 4 inches. The length will be 18 inches.
Now we can find the perimeter: 2(l + w) = 2(4+18) = 2 x 22 = 44 inches.

In which jobs we use perimeter and area?
What is the area of a 42 cm perimeter cube?
That depends how you define the perimeter for a cube. The term perimeter is usually used for plane figures, not for 3D solids.
How do you find area and perimeter with an algorithm?
To find the area and perimeter of a shape using an algorithm, you first need to define the shape's properties. For example, for a rectangle, you can use the formulas: area = length × width and perimeter = 2 × (length + width). The algorithm should take the necessary dimensions as input, compute the area and perimeter using these formulas, and then return the results. This approach can be adapted for different shapes by using their specific formulas.
What jobs use perimeter and area?
Some of the jobs that use area and perimeter include surveying, drafting and construction.
How could you define the perimeter of a non simple closed curve?
Multiply the area squared minus the radius
What should you use with area and perimeter square units or units?
units with perimeter square units with area
How can you use scale factor to find a new perimeter and area?
New perimeter = old perimeter*scale factor New area = Old area*scale factor2

In general, there is no relationship between area and perimeter.
Why do you need to use area and perimeter?
a lot of times area and perimeter is used to help with a lot of home improvement projects like
What math do you use to measure drywall?
area and perimeter.
Can perimeter be converted to surface area?
No. Perimeter does not uniquely define surface area. Example: Perimeter = 36 If it's a square with sides = 9, then area = 92 = 81 If it's a rectangle measuring 12 by 6, then area = 72 If it's a rectangle measuring 15 by 3, then area = 45 If it's a rectangle measuring 16 by 2, then area = 32 etc. etc. etc. Each of these figures has the same perimeter, but they all have different areas.
Can you define perimeter?
Perimeter is the sum of length of all sides of a geometrical figure.
