About Rectangle Calculator
The Rectangle Calculator is used to calculate the area, perimeter and diagonal of a rectangle.
Rectangle
In geometry, a rectangle is any quadrilateral with all four interior angles 90° (right angles).
Formulas
The following is the calculation formulas of the area, perimeter and diagonal of rectangle whose sides have width a and length b:
The perimeter of a rectangle
P = 2(a + b)
The area of a rectangle
A = ab
The diagonal of a rectangle
D = √a2 + b2
Where:
a, b = the width and length of a rectangle
P = the perimeter of a rectangle
A = the area of a rectangle
D = the diagonal of a rectangle
