Question

A plot of 10 $m^2$ is to be surfaced by tiles of area 100 $c{m}^2$. The number of tiles required = .

• A. 10
• B. 100
• C. 1000
• D. 10000

Answer 1

The correct option is C 1000

1 m = 100 cm.
Hence, 1 $m^2$ = 10000 $c{m}^2$.
So, the number of tiles required = $\frac{10\times 10000c{m}^2}{100c{m}^2}$ = 1000.
