Problem
A farmer needs to enclose a section of land in the shape of a parallelogram by using one side of a barn for one side. The barn and the side opposite of the barn will both be 11 feet long. One of the other sides will be 8 feet long. What is the length of the last side?
Step-by-step solution
In a parallelogram, opposite sides are equal in length. Since one side (the barn) is 11 feet and the side opposite it is also 11 feet, the other pair of opposite sides must also be equal. One of these sides is 8 feet, so the last side must also be 8 feet.
Answer
8 feet
