We had found area of square by counting squares.

But, that method is too long

To find area of any figure,

We use formula

For a square with side a

Area of square = a × a

= a
^{
2
}

Lets take a few examples

####
**
Find area of square with side 5 cm
**

**
**

Side of square = a = 5 cm

Area of square = a × a

= 5 × 5

= 25 square cm

= 25 cm
^{
2
}

####
**
Find area of square with side 2 m
**

**
**

Side of square = a = 2 m

Area of square = a × a

= 2 × 2

= 4 square m

= 4 m
^{
2
}
