The cost of putting a wire net around a rectangular field is 28000 at rupees 200 per metre if the length of the field is 40 m what is its width

Answer 1

therefore the width is 30 m

Answer 2

The width of filed is 30 m

Step-by-step explanation:

Cost of putting 1 m fence = rs.200

Length of fence for Rs.28000=$\frac{28000}{200}= 140 m$

Perimeter of field = 140 m

Length of field = 40 m

Perimeter of rectangular field =$2(l+b)=2(40+b)$2(l+b)=2(40+b)

2(40+b)=140

40+b=70

b=30

Hence The width of filed is 30 m
