Question

The total area of the floor is 360000 $c{m}^2$. Find the cost of tiling the floor if the charge of tiling is Rs. 20 / $m^2$.

• A. Rs. 360
• B. Rs. 3600
• C. Rs. 720
• D. Rs. 7200

Answer 1

The correct option is C

Rs. 720

100 cm = 1 m

1 $m^2$ = $\left(100cm\right)\times \left(100cm\right)$ = 10000 $c{m}^2$

Area of floor in $c{m}^2$ = 360000

$\therefore$ Area of floor in $m^2$ = (360000/10000) = 36 $m^2$

Given, cost of tiling = (Rs. 20 / $m^2$)

$\therefore$ Cost incurred for tiling the entire floor = $20\times 36$ = Rs. 720
