How do I find the length of a rectangle?
How do I calculate the length of a rectangle?
- If you have the area A and width w , its length w is determined as h = A/w .
- If you have the perimeter P and width w , its length can be found with h = P/2−w .
- If you have the diagonal d and width w , it’s length is h = √(d²−w²) .
How do you find the length and width of a rectangle calculator?
How do I calculate the width of a rectangle?
- If you have the area A and length h , its width w is w = A/h .
- If you have the perimeter P and length h , its width is w = P/2−h .
- If you have the diagonal d and length h , it’s width can be found with w = √(d²−h²) .
How do you find the length of a rectangle when given the area?
Let’s discuss how 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.
How do you find length when given area?
To find the length (L) of a rectangle given area (A) and width (W), you need to:
- Know the equation for a rectangle area is A = L × W.
- Determine L from that previous equation. L = A/Q.
How do you find the missing side length and perimeter of a rectangle?
To find the perimeter of a rectangle, add the lengths of the rectangle’s four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
How do you find length when given area and width?
To sum up: to find the length of a rectangle, you need to divide its area by the known width.
How do you find the length when you have the area and width?
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.
What is length and width 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 you find the length of a rectangle with the area?
How do you find the length of a rectangle if perimeter is given?
In the same way, if the perimeter and the width are known, the length can be calculated using the formula: Length(L) = P/2 – w. Where P = perimeter of the rectangle; and w = width of the rectangle.
