Answer:
2344.25 m2
Step-by-step explanation:
Total are of lawn taking paths is 60×45 , i.e. 2700m2
subtract area of paths
2700-(60×3.5 + 45×4.5)
=2700 - 367.5
=2332.5m2
paths are merging in between , therefore , we took the area in between double. so add that area once
2332.5 + 3.5×3.5
2332.5 + 12.25
= 2344.75m2
Area of remaining portion is 2344.75m2
