How do I find the length of a rectangle?

How do I calculate the length of a rectangle?

  1. If you have the area A and width w , its length w is determined as h = A/w .
  2. If you have the perimeter P and width w , its length can be found with h = P/2−w .
  3. If you have the diagonal d and width w , it’s length is h = √(d²−w²) .

What are the lengths of a rectangle?

A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).

How do I find the length of a rectangle if I only know the 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 calculate length?

Video quote: So in this example we have the data area is equal to 500 meter square width is equal to 10 meter to calculate the length we have the formula length is equal to area divided by width W.

What is the formula to find length?

Formulas for Arc Length

Arc Length Formula (if θ is in degrees) s = 2 π r (θ/360°)
Arc Length Formula (if θ is in radians) s = ϴ × r
Arc Length Formula in Integral Form s= ∫ a b 1 + ( d y d x ) 2 d x


How do you find the length and width of a rectangle?

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 find the length of a rectangle in 4th grade?

Video quote: And the formula is P equals 2 times L plus 2 times W. It means perimeter is equal to 2 times the length plus 2 times the width a rectangle is 5 feet long and 3 feet wide.

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

The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

How do you find the length and width?

Video quote: I get 20 minus 8 is 12. 12 is 2w I want to divide both sides by 2 here. And when I do that I'm going to get W equals 6. So in this particular rectangle. My width would be 6.

How do you find the perimeter of a rectangle without the length and width?

Video quote: Around or in other words all the side the sum of the sides all the sides added up you may know the perimeter of a rectangle formula.



How do you find the length and breadth of a rectangle if perimeter and area is given?

Video quote: So in our case perimeter will be twice length plus width right an area will be length times width from these defined variables.

How do you find the length and width of a perimeter calculator?

So, from the first formula above, we would get the following equation. It is the formula used by our length and width of a rectangle given perimeter calculator: L = (P/2) – W.

How do you find the length of the diagonal in a rectangle?

You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: d² = l² + w² , and now you should know how to find the diagonal of a rectangle explicit formula – just take a square root: d = √(l² + w²) .

How do you find the width of a rectangle calculator?

How do I calculate the width of a rectangle?

  1. If you have the area A and length h , its width w is w = A/h .
  2. If you have the perimeter P and length h , its width is w = P/2−h .
  3. If you have the diagonal d and length h , it’s width can be found with w = √(d²−h²) .

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

Find the dimensions of a rectangle with perimeter 100 m whose area is as large as possible.



  1. Explanation: Let ‘A’ be area and ‘P’ be perimeter of the rectangle. Let ‘x’ be the width and ‘y’ be the length. …
  2. Perimeter = 2 (length + breadth) Hence, P = 2(x+y) …
  3. Area of a rectangle = Length × Breadth. Hence,


How do you find the length of a square if you know the area?

All of its four sides are equal. This fact makes it especially easy to calculate the length of one of the sides, given the area of the square. If the area enclosed by the square is A, and the length of each side is L, then L = √A.

What is the formula of length of square?

length × width= length × length = length2 = 441 square cm. Thus length = √441 = 21 cm.

How do you find the length and width of a square foot?

Basic formula for square feet



To calculate feet squared (or sq. ft. for short), determine the length and width of the area you are working with, measured in feet. Multiply the length by the width and you’ll have the square feet.
