Question

13. The area of a rectangular plot is 616 square meter and
breadth is 22m. Find the length of the plot and the cost of
fencing at the rate of 7.50 rupees per metre​

Answer 1

Step-by-step explanation:

Area = l*b

616 = l*22

l = 616/22

l = 28

So, length of the plot is 28m

perimeter = 2(l+b)

= 2(28+22)

= 2*50

= 100m

cost of fencing 1m = Rs7.50

cost of fencing 100m = 7.50*100

= Rs750
