6. Pete is building a fence around a rectangular field. In his design, the length of the field is 62 feet and the width is 25 feet. The fence includes a gate that measures 9 feet in length.
After Pete builds the fence, he determines that he used 168 feet of fence material, not including
the gate. What is the percent error of Pete's design measurements compared to the actual fence
material used? Round your answer to the nearest hundredth of a percent.
