A room is 4.8 m long and 3.2 m wide. Its floor is to be constructed with square
marble tiles 10 cm x 10 cm. Find the number
tiles 10 cm x 10 cm. Find the number of tiles required to cover the floor and
the cost of the tiles at 18 per dozen.​

Answer 1

Step-by-step explanation:

length = 4.8m =480cm

breadth = 3.2m =320cm

this area of floor= 4.8×3.2

=153600cm square

thus area of one tile = 10×10

=100cm square

so no of tiles required= area of floor÷ area of one tile

= 153600÷100

=1536 tiles

no of dozens = 1536/12=128 dozens

thus total cost = 128×18=2304ruppes ans.
