Area of a Square
In area of a square we will learn how to find the area by counting squares.
To find the area of a region of a closed plane figure, we draw the figure on a centimeter squared paper and then count the number of squares enclosed by the figure.
We know, that square is a rectangle whose length and breadth are equal. in a square all four sides are equal.
Therefore, area of a square = (side × side) square units = (side)^2 square units.
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 cm^2. It can also be expressed as 2 cm × 2 cm = 4 cm^2. Area of a square is 2 times of its each side.
Solved examples to find the area of a square when side is given:
1. Find the area of a square of side 8 cm.
Area of a square = length (l) × length (l)
= 8 × 8 sq. cm.
= 64 sq. cm.
2. Find the area of a square of side 11 m.
Area of a square = length × length
= 11 × 11 sq. m.
= 121 sq. m.
3. Find the area of a square of side 49 cm.
Area of a square = length × length
= 49 × 49 sq. cm.
= 2401 sq. cm.
4. Find the area of a square of side 50 m.
Area of a square = length × length
= 50 × 50 sq. m.
= 2500 sq. m.
