How to find area of a rectangle - rectangle ABCD with sides a and b anf diagonal d
The image above shows a typical rectangle. It has four sides and four right angles. The lengths of its sides are denoted with a and b, while the length of the diagonal is denoted with d.
If all sides of the rectangle have equal lengths, it is called a square.
The area of a rectangle is a space restricted by its sides, or, in other words, within the perimeter of a rectangle. To find the area of a rectangle, all you need to do is a multiplication of rectangular sides a and b:
Area = a * b
Rectangle formulas
Our rectangle calculator has the following formulas implemented:
For the area of a rectangle: A = a * b
For the perimeter of a rectangle: P = 2 * (a + b)
For the diagonal of a rectangle: d² = a² + b²
