Question

how many square tiles of side 18 cm will be required to pave the floor of rectangle room 7.2 m ×5.4 m?​

Answer 1

Answer:

12000

Step-by-step explanation:

let no.of square tile required= n

area of one square tile = a*a

                                       =18*18= 324 cm2

length of floor                =7.2 * 100cm =720 cm

breadth of floor             = 5.4 * 100cm = 540 cm      

area of floor = l*b

                    = 720*540

                    = 388800    

ar.square*n = ar.rectangle

                 n =388800/324

                  n= 12000

hope this helped
