Twenty dots will cover one square inch. If a floor measures $5$ feet by $2.5$ feet, how many dots does it take to cover the floor?
$15, 000$
$36, 000$
$45, 000$
$1, 800$

Area of floor $=$ $5 \times 25 = 12.5$ sq.feet
1 sq.feet $= 144$ sq.inch $\Rightarrow$ $12.5 s q . f t = 144$ $\times$ $12.5$ sq.in
$1$ sq. in covered by $20$ dots, then $144$ $\times$ $12.5$ sq. in covered by
$= 144$ $\times$ $12.5$ $\times$ $20 = 36000$ dots
