Area, Perimeter and Diagonal of a Rectangle - Calculator
An easy to use online calculator to calculate the area, perimeter and diagonal of a
rectangle given its dimensions (length and width) is presented.
The formulas for the perimeter P, area A and length D of the diagonal of a rectangle of length L and width W are given by:
P = 2 L + 2 W
A = L W
D = √( L 2 + W 2 )
How to Find the Perimeter and Area of a Rectangle Using the Calcualator?
Enter the length L and width W as positive real numbers and press "Calculate Perimeter and Area". The outputs are the area A, perimeter P and diagonal D of the rectangle.
