Question

A square field has an area of 6.25 km^2.Find the cost of putting a fence round it at RS 10.50 per metre

Answer 1

let side of square be a
Area = a²
a=√6.25
a=2.5

perimeter=4a=4(2.5)
=10km
10,000m
cost of putting a fence per m=₹10.5
cost of fencing on 10,000m= 10.5×10,000
=105,000

Answer 2

a square field =6.25km^2
the cost of fencing= 10.50×6.25
=6562.5
hence the costof fencing is 6562.5
