The rectangle is the most common quadrilateral. A parallelogram with all internal angles measuring 90º is called as a rectangle. It is four sided polygon made of length a and breadth b.

Rectangular Calculator is an easy online tool to find the area, perimeter and polygon diagonal of the rectangle.

## Rectangle Parameters Steps

Steps for finding Rectangular parameters:
Step 1: Read the given problem and note down the sides a and b

Step 2: Find area, perimeter and polygon diagonals using the formula
Area of rectangle = a $\times$ b
Perimeter of rectangle = 2a + 2b
Polygon diagonals of rectangle = $\sqrt{a^{2} + b^{2}}$
Here a and b are side length and breadth. Substitute these values and get the answer.
