## Square & its Formulas

The below mathematical formulas are used in this square calculator to find area, perimeter & diagonal length of a square

### Solved Example

The below solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the area, perimeter & diagonal length of a square.

Example Problem :
Find the area, perimeter & diagonal length of a square having the sides of 9 cm?

Solution :
The given
side = 9 cm

Step by step calculation
formula to find area = side x side
substitute the values
= 9 x 9
= 81

formula to find perimeter = 4 x side
substitute the values
= 4 x 9
= 36

formula to find diagonal length = √2 x side
substitute the values
= √2 x 9
= 12.7279
