Question

The dimensions of the floor of a rectangular hall are 4m X 3m. The tiles floor of the hall is to be tiled with regular tiles with 8 cm X 6 cm dimensions without breaking tiles to smaller size. The number of tiles required:

• A. 4800
• B. 2600
• C. 2500
• D. 2400

Answer 1

The correct option is C 2500

Length of hall$=4m=400cm$

Breadth of hall$=3m=300$cm

$\Rightarrow$ Area of taken$=400\times 300$

$=120000c{m}^2$

Area of each tile$=8\times 6=48c{m}^2$

Let number of tiles$=x$

$\Rightarrow$ Total area curved$=x\times$Area of each tile

$120000=x\left(48\right)$

$\Rightarrow x=\frac{120000}{48}=2500$.
