Rectangle calculator, formula, work with steps, step by step calculation, real world and practice problems to learn how to find the area, perimeter & diagonal length of a rectangle in inches, feet, meters, centimeters and millimeters.
The formula for the area of a rectangle is width x height, as seen in the figure below:
The area of any rectangular place is or surface is its length multiplied by its width. For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards.
a = length side a b = length side b p = q = diagonals P = perimeter A = area √ = square root
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.
