Question

Each rectangular tile is 40 cm long and 30 cm wide how many tiles are required to Cover the Floor of a room with length 4.8 m and breadth 2.4 m

Answer 1

Answer:

96 tiles

Step-by-step explanation:

firstly we need to find the area of a tile.

then the area of the room.

divide the area of the room by the area of a tile .

area of rectangle = l * b = length * breadth

area of tile = l * b = 40 * 30 = 1200 sq.cm    --( 1 )

area of room= (units are different .therefore we must convert it into cm)

=480 cm * 240cm= 115200 sq.cm----( 2 )

no. of tiles required = area of the room / area of 1 tile

= 115200/1200

=96 tiles
