A rectangular garden 20 m × 14 m has four full circular flowerbeds of radius 2 m placed within it. What is the area left for grass?
Show answer & explanation
Correct answer: A
Explanation
Area of the rectangular garden = 20 × 14 = 280 m²
Area of one circular flower bed = π × 2² = 4π
Total area of four flower beds = 4 × 4π = 16π ≈ 50.3 m²
Area remaining for grass = 280 − 50.3 ≈ 229.7 m²
