# The dimension of a floor of a rectangular hall are 4 m. x 3 m., The floor of the hall is to be tiled fully with 8 cm. x 6 cm. rectangular tiles without breaking into smaller sizes. The number of tiles required is

 A) 4800 B) 2600 C) 2500 D) 2400

 C) 2500

Area of the floor = $$\Large 4m \times 3m$$

=$$\Large 400\ cm. \times 300\ cm.$$

Area of one tile = $$\Large 8\ cm \times 6\ cm.$$

Number of tiles required = $$\Large \frac{area\ of\ the\ floor}{area\ of\ the\ tile}$$

=$$\Large \frac{400 \times 30}{8 \times 6} = 50 \times 50$$

= 2500
