Answer is 6165.25m sq

Step-by-step explanation:

Area of school playground is

160m×80m=12800m sq

Area kept for swings = 80m×80m=6400m sq

Area common to both paths = 1.5×1.5=2.25m sq

Total area covered by both paths

(80m×1.5m=12.0m sq) again multiply

(80m×1.5m=12.0m sq)

(12.0+12.0-2.25)

237.75m sq

Area covers by grass = area of school playground-area kept for swings +area covers by paths

12800-6400+237.75

12800-6637.75

And answer is = 6165.25m sq
