Area of a Square Formula
Before getting to the area of square formula used for calculating the region occupied,
let us try using a graph paper. You are required to find the area of a side 5 cm. Using
this dimension, draw a square on a graph paper having 1 cm × 1 cm squares. The
square covers 25 complete squares.
Thus, the area of the square is 25 square cm, which can be written as 5 cm × 5 cm,
that is, side × side.
From the above discussion, it can be inferred that the formula can give the area of a
square is:
Area of a Square = Side × Side
2
Therefore, the area of square = Side square units
Here some of the unit conversion lists are provided for reference. Some conversions
of units:
1 m = 100 cm
1 sq. m = 10,000 sq. cm
1 km = 1000 m
1 sq. km = 1,000,000 sq. m
Area of a Rectangle Formula:
