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?

We are asked to solve and determine the total yards that Jules needed to fence his land. Initially, we have an original  square lot area of 30 yards by 30 yards. Then it is divided by two and we need to compute for the new perimeter of the land so that we will know the total fence that we need.The solution for the perimeter is shown below:
Perimeter = 30 +15 + 15 + 30 + 15+ 15 + 30 (the middle)
Perimeter = 150 yards

Jules needs 150 yards to fence his land.
