24 Οκτ 2024 · 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/W. To sum up: to find the length of a rectangle, you need to divide its area by the known width.
The length of a rectangle can be calculated using the following formulas that have been derived from the area and perimeter formulas, Length = Area of rectangle ÷ Width; and Length = (Perimeter ÷ 2) - width.
The formula of area of rectangle is: \ (\begin {array} {l}A = Length \times Width \;\; unit^ {2}\end {array} \) Diagonal of a Rectangle. A rectangle has two diagonals, that bisects each other. Both the diagonals are equal in length. Length of Diagonals. The rectangle is a symmetrical shape and has both the diagonals equal in length.
Question: Find out the length of the rectangle if the area is 96 cm 2 and the breadth is 16 cm. Solution: As we know, the Area of a rectangle = l × b. Here the area is already given, so find the length of the rectangle. So,96= l × 16. =>l= 96 ⁄ 16 i.e. Length = 6 cm. Rectangle formulas are given here.
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). If the rectangle's width is not known, you'd need to simultaneously solve the system of equations above to get the length h.
A rectangle has two diagonals, they are equal in length and intersect in the middle. A diagonal's length is the square root of (a squared + b squared): Diagonal "d" = √ (a 2 + b 2) Example: A rectangle is 12 cm wide, and 5 cm tall, what is the length of a diagonal? d = √ (122 + 52) = √ (144 + 25) = √169. = 13 cm. Golden Rectangle.
Length of Rectangle Formula: If we've area of a rectangle is A; the breadth of a rectangle is B and the length of the rectangle is going to be L; so.
