if you tell me right answer I will mark you as brain list please friends ​

Answer 1

Answer:

Area = l× b

= 240 × 159 = 38160 m² Or 38.16 km²

Step-by-step explanation:

Perimeter = 2(l+b) = 2(240 + 159) = 2× 399 = 798m

Cost of fencing 1m = ₹30

Cost of fencing 798m = 798 × 30 = ₹23940

Answer 2

length of field = 240 m

breadth of field = 159 m

area of rectangle = l × b

= 240 × 159

= 38160 square m

cost of fencing per square metre = Rs.30

cost of fencing per 38160 square metre = 38160 × 30

= rs.1144800
