A square field has side 35 m and contains a circular pond. If the area of the pond is 770 m², what is the remaining area of the field?

1. 455 m²
2. 480 m²
3. 505 m²
4. 545 m²

Correct answer: 455 m²

Solution

Area of the square = \(35^2 = 1225\) m². Subtract the pond area \(770\) m² to get remaining area \(1225 - 770 = 455\) m².
