Answer 1

We know that,

Area of a rectangle = Length × Breadth

Area of the floor of kitchen = (Length × Breadth)

= (320 × 150) square cm.

Also, we know that

Area of a square = Side × Side

Area of one tile = (5 × 5) square cm

Number of tiles required

$= \frac{area \: of \: the \: floor}{area \: of \: one \: tile}$

$= \frac{320 \times 150}{5 \times 5}$

$= 32 \times 15 = 480$
