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.

Nov 3, 2020 · 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 \(L = \frac{A}{W}\) If you know the length and want the width, rearrange to get \(W = \frac{A}{L}\)

Feb 6, 2024 · Use this calculator if you know 2 values for the rectangle, including 1 side length, along with area, perimeter or diagonals and you can calculate the other 3 rectangle variables. A square calculator is a special case of the rectangle where the lengths of a and b are equal.

This length and width of a rectangle given perimeter calculator will help you to find the unknown side of a rectangle using the perimeter value.

The width of a rectangle calculator can take two dimensions of your rectangle (height, area, diagonal, or perimeter) and work out the width of your rectangle. We'll also show you some formulas for the width of a rectangle , that are based on what information you have available.

Calculate any property of a rectangle, including the area, perimeter, length, width, or diagonals using our rectangle calculator.

The rectangle solver finds missing width, length, diagonal, area or perimeter of a rectangle. The calculator accepts all types of input values, including fractions and square roots, and provides step-by-step explanation.

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'. Then substitute the value of width in the formula of the perimeter of a rectangle and simplify the value of length 'l', that is, P = 2 (l + A/I).

Online calculator to calculate the dimensions (length and width) of a rectangle given the area A and perimeter P of the rectangle. Formula for Area and Perimeter of 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
