Question

a woman fences a 3m by 4m rectangular plot to keep her chickens in. The fencing costs 200 naira per meter. How much does it cost to fence the plot?

Answer 1

First we will find the circumference of the rectangular plot:

C = 2(3 + 4)

C = 14 m

Since the fencing cost ₹1.20 per meter, 14 meters of fence will cost 14 times that amount:

14× 1.20 = ₹16.80

It costs ₹16.80 to fence the plot.
