Question

A floor 10m × 7m is to be paved with square tiles of side 50cm. Find the number of tiles required:​

Answer 1

Answer:

Area of floor =( 10×7 )m

side if square tile = 50 cm = 0.5m

$number \: of \: tiles \: = \frac{area \: of \: floor}{area \: of \: each \: tile}$

$= \ \frac{10 \times 7}{0.5 \times 0.5}$

$= \frac{10 \times 7 \times 100}{5 \times 5}$

$= 280 \: tiles$
