Question

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

Answer 1

Length of the floor =16m

Breadth of floor =11m

Area of floor =16*11

=176m sq

Area of one tile =40*40

=1600cm sq or 16msq

Therefore number of tiles required =176/16

=11

Therefore number of tiles =11

Answer 2

Step-by-step explanation:

QUESTION:–

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.

GIVEN:–

Length of floor=16m OR 1600cm

Breadth of floor=11m OR 1100cm

Length of square tiles=40cm

FIND:–

The number of tiles required.

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

ANSWER:–

1100 tiles
