In a square the length is equal to breadth.
Hence, area of a square = side × side
The number of 1 cm squares enclosed = 4
Area = 4 sq cm
4 = 2 × 2
Hence, area = side × side
The unit of sides and the corresponding units of areas as given below:
Unit of Side
Unit of Area
mm
square mm (sq mm) or mm2
cm
square cm (sq cm) or cm2
m
square m (sq m) or m2
km
square km (sq km) or km2
Note: Write finding the area of a given figure, make sure that the sides (length or breadth) are in the same unit of length. If they are given in different units, change them to the same unit.

Look at the above figure. You can see that the area of a square having sides 2 cm each is equal to the area of 4 squares of sides 1 cm each = 4 cm2. It can also be expressed as 2 cm × 2 cm = 4 cm2. Area of a square is 2 times of its each side.
