Question

Karan wants to cover the floor of his room with lavish tiles. His room is square in shape with sides of 6 m. The shopkeeper told him that the area of each tile is 0.5 m². Can you tell how many tiles Karan should buy?

• A. 108
• B. 36
• C. 72
• D. 144

Answer 1

The correct option is C

72

Given a square room of side = 6 m.
Area of each tile = 0.5 m²
We know that, area of a square = Side $\times$ Side
$\therefore$ Area of a square room
= 6 $\times$ 6 = 36 m².

So, number of tiles required
= $\frac{\text{Area of room}}{\text{Area of a single tile}}$
= $\frac{36}{0.5}$ = 72
Hence, Karan should buy 72 tiles to cover the floor of his room.
