The floor of a rectangular room measures 16 m by 11 m. the floor has to be tiled with square tiles of length 40 cm. Find the number of tiles required.

$\large{\red{\mathcal{GIVEN:–}}}$

Length of floor=16m OR 1600cm

Breadth of floor=11m OR 1100cm

Length of square tiles=40cm

$\large{\red{\mathcal{FIND:–}}}$

The number of tiles required.

$\large{\red{\mathcal{SOLUTION:–}}}$

AREA OF THE FLOOR=LENGTH × BREADTH

=(1600 × 1100)cm²

=1,760,000cm²

AREA OF A TILE=SIDE × SIDE

=(40 × 40)cm²

=1600cm²

therefore, number of tiles required

=1,760,000/1600

=1,100

$\large{\red{\mathcal{ANSWER:–}}}$

1100 tiles
