Question

A floor of a room is 9m *6.75m. It is to be paved with square tiles of the marble of the same size. Find the greatest measurement of tiles. Find least possible number of such tiles.

Answer 1

Answer:

for this we need to take out HCF of 9m &6.75m

or

900cm & 675cm

900= 2*5*2*5*3*3

675=3*3*5*5*3

HCF=3*3*5*5

=225

Answer 2

Area of the floor = 9m × 6.75m = 60.75m

Let side of the tiles be s

ATP

(s)^2 = 60.75

s = 7.79422863

Area of the square tiles = (side)^2

= (7.79422863×7.79422863)

= 60.7499999

No of tiles = 60.75/60.7499999

= 100.000002 tiles
