How do you find the length and width of a rectangle with the area?
To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is, ‘w = A/l’.
How do you find the length of a rectangle with 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 do you find the length of area?
Because a square has four sides of equal length, the area is given by A = L2. If you know the area, you can immediately determine the length of each side, because it’s the square root of the area. The length of each side of the square is the square root of 20, which is 4.47 meters.
How to calculate the length and width of a rectangle?
The formulas for the perimeter P and the area A of the rectangle are used to write equations as follows: P = 2 * L + 2 * W A = L * W Then these equations are solved for L and W which are the length and width of the rectangle.
How to calculate the perimeter of a rectangle?
Here are the basic formulas used by the calculator. Perimeter (distance around the outside of the rectangle) = a + a + b + b or 2 a + 2 b and is noted as (P) Diagonal is d ² = a ² + b ² which is the Pythagorean Theorem (see our Pythagorean Theorem calculator ). Example of calculating the area of a rectangle:
How to calculate the area of a rectangular shape?
The formula used by this calculator to calculate the area of a rectangular shape is: A = L · W. Symbols. A= Area; L = Length; W = Width; Area Dimensions – Length & Width. Enter the measurements for length and width for the rectangular shape you are calculating, and select the appropriate units for each measurement value entered.
When do you call a rectangle a square?
If the lengths of the sides are all the same, then the rectangle is also a square. The lengths of the sides will be given as a or b or you can use l and w for “length” and “width”. The diagonal, which goes from one vertex to the opposite vertex cutting the rectangle into two squares, is called the diagonal and noted as d.
