Question

A rectangular field has to be fenced on three sides leaving one side of 20 feet uncovered. If the area of the field is 680 sq. feet, how many feet of fencing will be required?

1. A. 95
2. B. 92
3. C. 88 (Correct answer)
4. D. 82

Correct Answer

Option C — 88

Detailed Solution & Explanation

The correct answer is 88.

Key Points

• The uncovered side = 20 feet.
• Area = length × width = 680 sq. ft.
• Width = 680 ÷ 20 = 34 feet.
• Fencing required = two widths + one length (3 sides) = 34 + 34 + 20 = 88 feet.
