area of floor = 120 m^2
area of one tile = .5*.25 or .125 m^2
number of tiles = 120/.125 = 960
or
we need 30 tiles along one wall, and 32 along the other wall, so 30*32 or 960 tiles
carpet is 13 by 6 or 78 m^2, leaving
120-78 or 42 m^2 of the floor exposed
A floor which measures 15m*8m is to be laid with tiles measuring 50cm by 25 cm. Find the number of tiles required. Further, if a carpet is laid on the floor so that a space of 1m exists between its edges and the edges of the floor, what fraction of the floor is uncovered?
