Cost of laying sand on this path = Rs. 1372 at the rate of Rs. 7 per sq. m
Step-by-step explanation:
[ refer to attachment ]
Area of field + path = L × B
=> 35 × 18
=> 630 m² -------------(1)
Area of field = L× B
=> 31 × 14
=> 434 m² --------------- (2)
Area of path = area 1 - area 2
=> 630 - 434
=> 196 m²
Given Rate = Rs. 7/ m²
If cost of 1m² = Rs. 7
Cost of 196m² = 7×196
=> Rs. 1372
