(ii) = 2*195*40 = 15600
Answer:
Step-by-step explanation:
Given :-
Length of the field = 120 m
Breadth of the field = 75 m
Solution :-
(i) Area of the field = L × B
= L × B
= (120 × 75) m²
= 9000 m²
Cost of turfing the field = ₹ 15
= ₹ (9000 × 15)
= ₹ 135000.
(ii) Perimeter of the field = 2(L + B)
= 2(L + B)
= 2(120 + 75)
= 390 m
The cost of fencing = ₹ 40.
= ₹(390 × 40)
= ₹ 15600.
