Question

A flooring tile has the shape of a parallelogram whose base is $24cm$ and the corresponding height is $10cm$. How many such tiles are required to cover a floor of area $1080$ $m^2$?

• A. $20000$
• B. $35000$
• C. $45000$
• D. $65000$

Answer 1

The correct option is C $45000$

Area of the parallelogram $=$ Base$\times$Height

So area of each tiles $=24\times 10=240c{m}^2$

Area of the floor $=1080m^2=(1080\times 100\times 100)c{m}^2$

$\therefore$ Required number of tiles $=\frac{\text{Area of the floor}}{\text{Area of each tiles}}=\frac{10800000}{240}=45000$
