Answer 2

Total cost of fencing will be Rs.15000

So option (c) will be correct answer

Step-by-step explanation:

We have given length of the rectangular field l = 100 m

And breadth of the rectangular field b = 50 m

Perimeter of rectangle is equal to $P=2(l+b)$, here l is length of rectangle and b is breadth of rectangle

So perimeter will be equal to $P=2\times (100+50)=300m$

We know that 1 m = 100 cm

So 300 m = 300×100 = 30000 cm

It is given that fencing expenses is 50 paise per cm , that is 0.5 Rs. per cm

So total cost of fencing = 30000×0.5 = Rs.15000

So option (C) will be correct answer
