Area of the road parallel to the length = 5m × 80m
=400m^2
Area of the road parallel to the breadth = 5m × 60m
= 300m^2
The overlapping area of the road at their cross section
=5m × 5m
= 25m^2
Total area of the road
= (300+400-25) m^2
=675m^2
No. of stones for paving the road = (675 ÷ 0.5)
= 1350
Hope this will help...please do thanks me.
