Question

The area of a rectangular park is 456 square metre and its length is 24 metre . Find the breadth of the park and the cost of fencing it at the rate of rupees 8.50 per metrr

Answer 1

Here is your answer, mark me as brainly

Answer 2

Area = (l)(b)

456 = 24(b)

b = 19m

Length of fence = perimeter

= 2(l+b) = 2(24+19) = 2(43) = 86m

So, cost will be 8.50x86 = 731

Hence, the answer is ₹731.
