Question

A flooring tile has the shape of a parallelogram whose base is 20 𝑐𝑚 and the corresponding height is 12 𝑐𝑚. How many such tiles are required to cover a floor of area 1080 $m^2$?

• A. 36000
• B. 45000
• C. 54000
• D. 30000

Answer 1

The correct option is B 45000

$Areaofthefloor=1080m^2$
$=1080\times 10000c{m}^2=10800000c{m}^2$
$[\because 1m^2=10000c{m}^2]$
$Areaofonetile=base\times height$
$=20\times 12=240c{m}^2$
$Numberoftilesrequired$
$=\frac{Areaoffloor}{Areaofonetile}$
$=\frac{10800000}{240}$
$=45000tiles$
