The formula for the area of the square is length multiplied by width.
Perimeter = 4 times the square root of the area.
The perimeter of a square is four times the length of any side. The area is the length of a side multiplied by itself (which is to say, squared).
We can calculate the area by taking out the product of the length and the breadth of the house
It is the same as its length, and if that is not given, it is the square root of the area.
