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

🏞️ Let’s Solve the Fencing Problem! 🤔
We know:
– The area of the field is 680 sq. feet.
– One side of the field is 20 feet long and won’t be fenced.
Let’s use the formula for the area of a rectangle:
Area = Length × Width
We know the area (680 sq. feet) and one side (20 feet). Let’s call the other side “width”. Then:
680 = 20 × Width
Now, divide both sides by 20:
Width = 680 ÷ 20
= 34 feet
So, the width of the field is 34 feet.
Now, let’s calculate the fencing required. We need to fence three sides:
– Two widths (34 feet each)
– One length (20 feet)
Total fencing required = 2 × 34 + 20
= 68 + 20
= 88 feet
Final Answer: 88 feet of fencing will be required. 🏗️
