Square tiles

The room has dimensions of 12 meters and 5.6 meters. Determine the number of square tiles and their largest dimension to exactly cover the floor.

Correct answer:

n =  105
a =  80 cm

Step-by-step explanation:

x=12 m cm=12 100  cm=1200 cm y=5.6 m cm=5.6 100  cm=560 cm  1200=24352 560=2457 GCD(1200,560)=245=80  a=GCD(x,y)=GCD(1200,560)=80 cm  S1=x y=1200 560=672000 cm2 S2=a a=80 80=6400 cm2  n=S1/S2=672000/6400=105
