How do you find length and width from perimeter?
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
How do you get area from perimeter?
Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5.

The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.
How do you find the length when you have the area and width?
A = L * W, where A is the area, L is the length, W is the width or breadth. NOTE: When multiplying the length by the width, always ensure you work in the same unit of length.

How do you find breadth when given length and area?
To find Length or Breadth when Area of a Rectangle is given
- When we need to find length of a rectangle we need to divide area by breadth.
- Length of a rectangle = Area ÷ breadth.
- ℓ = A ÷ b.
- Similarly, when we need to find breadth of a rectangle we need to divide area by length.
- Breadth of a rectangle = Area ÷ length.
How big is a 28 foot dog pen?
* 28 feet fencing ==> perimeter of the rectangle is 28 feet. * width of the pen is 2 feet more than one-half the length. Let us assume that , length = x feet. Again multiply throughout by 2. Subtract 4 from both sides…. ==> width 4 + 2 = 6 feet. Hence the answer.
