Question

Find the cost of selecting a fence around a square field whose area is 9 hectares, if fencing cost rupees 3.50 per metre.

Answer 1

Step-by-step explanation:

1 hectare=10000m^2

so 9 hectares =90000m^2

area=90000m^2

so side= rootunder90000=300m

perimeter =4×300=1200m

cost of one metere fencing =35rupees

hence cost of 1200m fencing =1200×35=42000rupees
