Answer 1

Answer:

240

Step-by-step explanation:

area of marble tiles = 25×20 = 500cm^2

4m = 4×100 = 400cm

3m = 3×100 = 300cm

areaof wall = 400×300 = 120000cm^2

no. of tiles required = 120000/500 cm^2

= 240

Answer 2

lenght of wall =4m =400cm

breath of wall=3m=300cm

area of wall =length×breath

=400×300

=120000cm^2

area of tiles =25×20=500cm^2

so ..

no of tiles required =

=area of wall÷area of tiles

=120000/500 =1200/5

=240 tiles...ans
