Jules owns a square plot of land that measures 30 yards on each side. he plans to divide the land in half by building a fence, as shown by the dotted line below. how many yards of fencing will jules need?
a) 15 yd
b) 30 yd
c) 30 square root 2 yd
d) 30 square root 3 yd

This is the concept of algebra, given that Jules owns a square piece of land that he wants to divide into two. Upon this division we know that the length of the fence will take the length of the land. Therefore since the fence will cut through the the land, the length of the fence will be 30 yd
