Answer»

Area of first room A1= length * breadth= 5*3 = 15 sq m

Area of second floor A2= length * breadth= 6*5 = 30 sq m

Area of tile At= side*side =.5*.5=.25 sq m

Let number of tiles required = n

Then,n*At = A1 + A2n = (15 + 30)/.25n = 45*100/25 = 45*4n = 180

Therefore number of tiles required = 180
