Question

A marble tile measures 25cm length and 30cm breadth. Find the no. of tiles required to cover the floor of the room of size 4m by 3m...(I am confused we have to find area or perimeter)

Answer 1

Answer:

(4*3)/(0.25*0.30)=160

Step-by-step explanation:

The area of room = 4 *3 =12 sq.m

The area of tile = 0.25* 0.30=0.08 sq.m

therefore the number of tiles required for the room = room area / tile area

                                                                                      = 12/0.08

                                                                                       =160 tiles.

Answer 2

$the \: no. \: of \: tiles \: required \: to \: cover \: the floor \: of \: the \: room =(4 \times 3) \div (0.25 \times 0.3) \: \: \: \: \: = 12 \div 0.075 \: \: \: \: \: = 160 tiles\: answer$
