Question

a rectangular has its length and breadth in ratio 5:3 if its area is 3.75 hectares then cost of fencing 25 per metre is​

Answer 1

Answer:

Step-by-step explanation:

let the length and breadth be 5x,3x respectively

area=3.75 hectares

to find the length and breadth,

5x+3x=375/100

8x=375/100

x=375/(100*8)

x=375/800

x=0.46875

length=5x

=5*0.46875

=2.34(approx)

breadth=3x

=3(0.46875)

=1.41(approx)

as we will fence the perimeter,

perimeter=2(l+b)

2(2.34 + 1.41)

2(3.75)

7.5m

cost of fencing = 25/m

25*7.5

187.5
