Length= 45 m
Breadth= L-15= 45-15= 30m
(a) We have to find the area.
Area= L×B
Area= 45×30= 1350m²
Cost of levelling for 1m²= ₹5
Cost of levelling for 1350m²= 5×1350= ₹6750
(b) We have to find the perimeter
Perimeter= 2(l+b)
Perimeter= 2(45+30)=2(75)
= 150 m
Cost of fencing 1m = ₹7
Cost of fencing 150m = 7×150= ₹1050
