How do you find the length of a rectangle with area?

To find Length or Breadth when Area of a Rectangle is given

  1. When we need to find length of a rectangle we need to divide area by breadth.
  2. Length of a rectangle = Area ÷ breadth.
  3. ℓ = A ÷ b.
  4. Similarly, when we need to find breadth of a rectangle we need to divide area by length.
  5. Breadth of a rectangle = Area ÷ length.

How do you find the area and the perimeter of a rectangle?

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 length when you have 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. If they are given in different units, change them to the same unit. Let’s work out a few example problems about the area of a rectangle.

How to calculate the area of a rectangle given its sides?

Use this calculator to easily calculate the area of a rectangle given its sides (length and width) in any metric: mm, cm, meters, km, inches, feet, yards, miles… How to calculate the area of a rectangle? The formula for the area of a rectangle is width x height, as seen in the figure below:

How do you calculate square feet for a rectangle?

For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards. A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 = 180 square feet.

What is the formula to find the perimeter of a rectangle?

To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b) P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b)

What is the distance around a rectangle called?

The distance around a rectangle is called the perimeter of the rectangle. It is usually denoted by P P. To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is
