In the family house, they will line the hall with 6m * 10m tiles with dimensions of 25cm * 35cm. How many tiles do they consume if they have to count on a tenth of the waste?

Correct answer:

n =  755

Step-by-step explanation:

a=6 m b=10 m  x=25 cm m=25:100  m=0.25 m y=35 cm m=35:100  m=0.35 m  S1=a b=6 10=60 m2 S2=x y=0.25 0.35=807=0.0875 m2  n1=S1/S2=60/0.0875=686  n=n1+n1/10=686+686/10=755
