Answer:
Length of a lawn(l) = 115m
Breadth of a lawn (b) = 64 m
Width of lengthwise road(PQ)= 2.5 m
Width of breadththwise road (AB)= 2 m.
Area of road( ABCD)= 115×2= 230 m²
Area of road( PQRS)= 64×2.5= 160 m²
Area of common path EFGH= 2× 2.5= 5 m²
Area of the roads= (Area of road ABCD+ Area of road PQRS) - Area of Road EFGH
Area of the roads= 230+160-5
Area of the roads= 390-5= 385 m²
Rate of gravel = ₹ 4.60 per m²
Cost of gravelling the roads= 385 × 4.60= 1771
Hence, the Cost of gravelling the roads = ₹1771
