How To Find The Length Of A Rectangle?

What is the formula for length?

This can be expressed in the following equation, where is the length and is the width of the rectangle.

Since the area of the rectangle is equal to its length multiplied by its width ( \displaystyle A = l * w), and the area of the rectangle is given, the following equation must be true.

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

To find the width of a rectangle, use the formula: area = length × width. Just plug the area and length of the rectangle into the formula and solve for the width. If you don’t have the area, you can use the rectangle’s perimeter instead. In that case, you would use the formula: perimeter = 2 × length plus 2 × width.

How do you find the length and width?

The area of a rectangle (A) is related to the length (L) and width (W) of its sides by the following relationship: A = L ⋅ W. If you know the width, it’s easy to find the length by rearranging this equation to get L = A ÷ W. If you know the length and want the width, rearrange to get W = A ÷ L.

How do you find the length of a shape?

Explanation: 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 calculator?

Rectangle calc: find P (perimeter)

  • Choose the length of the rectangle – a = 5 cm in our case.
  • Decide on the width of the rectangle – e.g. b = 6 cm .
  • Add these two values: a + b = 5 + 6 = 11 cm .
  • Multiply the result by 2: P = 2 * 11 = 22 cm .
  • Here we go! The perimeter of our rectangle is 22 cm.

How are dimensions written?

Amazon writes it as:Length x Width x height in the “product dimension” area. It needs to be written Length X Width X Height. That is standard for measurements.

What is the width formula?

To find the width of a rectangle, use the formula: area = length × width. Just plug the area and length of the rectangle into the formula and solve for the width. If you don’t have the area, you can use the rectangle’s perimeter instead. In that case, you would use the formula: perimeter = 2 × length plus 2 × width.
