Question

A rectangular floor of length 15 metres and
width 12 metres has to be
placed with ceramic tiles of length 15 cm and width 12 cm. How many
ceramic tiles are needed to make the floor?
( solve the problem with steps )​

Answer 1

Number of tiles required to cover the entire floor is 10000

Step-by-step explanation:

We Have :-

Rectangular Floor -

Length = 15 m

Width = 12 m

Ceramic Tiles -

Length = 15 cm

Breadth = 12 cm

To Find :-

Ceramic tiles needed to make the floor

Formula Used :-

Area of Rectangle = Length × Breadth

Solution :-

Area of Floor :-

Area of Rectangle = Length × Breadth

Area = 15 m × 12 m

Area = 1500 cm × 1200 cm

Area = 1800000 cm²

Area of Tile :-

Area of Rectangle = Length × Breadth

Area = 15 cm × 12 cm

Area = 180 cm²

Tiles Required :-

$tiles \: required = \dfrac{area \: of \: the \: floor}{area \: of \: the \: tile} \\ \\ tiles = \dfrac{1800000}{180} \\ \\ tiles = 10000$

Number of tiles required to cover the entire floor is 10000
