A farmer divides his ranch into 10 equal squares. The side length of each square section is 20 m. Calculate the total area of the ranch.

Area = (side)^2

Area = (20cm)^2

Area = 400cm^2 = the area of one square.

Let T = total area

T = 10(Area)

T = 10(400cm^2)

T = 4,000cm^2

Done.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
