Question

The area of a rectangular park is 4100 m2 and its breadth is 50 m. Find the cost of fencing
it at ₹ 30 per metre.​

Answer 1

Answer:

$area = 4100 {m}^{2} \\ breadth = 50 \:m \\ length = \frac{area}{breadth} \\ length = \frac{4100}{50} = 82 \: m \:$perimeter= 2(l+b) =2(82+50)=2(132)=264 m

cost of fencing=264×30=rs 7920

Answer 2

Answer:

area of rectangular park= l×b

4100=l×50

4100÷50 = L

82 = L

perimeter of park= 2 (l+b)

= 2 (82+50)

=264

cost of fencing = 264 × 30

= 7920
