Answer 1

Answer:

Rs.560

Step-by-step explanation:

Double fencing = 2 time ...

So...

wire needed = perimeter × 2

= 40 × 2

= 80 metres

Cost of wire = Length of wire × cost of per meter wire...

= 80 × Rs. 7

= Rs.560

Therefore the cost is Rs . 560

Answer 2

Answer:

according to question :-

perimeter = 40 m

and in question it said double fencing so we have to do double perimeter so :-

perimeter *2 = 40*2 = 80m

now according to question :-

1 m = ₹7

so 80 m = 7/1*80 = 7*80= ₹560
