Quizplus · Accepted Answer

To minimize the perimeter of a rectangle with a fixed area, the rectangle should be as close to a square as possible. The area is 91 ft², so the side length of the square would be $\sqrt{91} \approx 9.54$ ft. Thus, the dimensions should be approximately $9.54 \mathrm{ft} \times 9.54 \mathrm{ft}$.
