Question

A flooring tile has the shape of a parallelogram whose base is 24 cm and the corresponding height is 10 cm. How many such tiles are required to cover a floor of area 1080 $m^2$? (If required you can split the tiles in whatever way you want to fill up the corners).

• A. 22500
• B. 50000
• C. 40000
• D. 45000

Answer 1

Answer: (D)

45000

Given,
$l=24cm$ (of a tile)
$b=10cm$ (of a tile )
Area of a tile (in parallelogram shape) $=l\times b{cm}^2$
$=24\times 10$
$=240{cm}^2$
Total floor area $=1080m^2$
$10000{cm}^2$ = $1m^2$

Required number of tiles to cover the floor area $=\frac{1080\times 10000}{240}$
$=45000$
