Question

Mr. Randeep is having a rectangular garden of length 7\6 m and breadth
$1 \frac{1}{2}$
m. He decides to plant a few marigold plants in his garden. If each of the length and breadth of the rectangular garden is increased by 2 m, then
(a) Find the new area of the rectangular garden.
(b) If the cost of fencing the rectangular garden by a barbed wire is Rs.120 per metre. Then calculate the cost of fencing the new garden​

Answer 1

Answer:

Area: 133/12 m

Cost: Rs.1600

Step-by-step explanation:

New length = 7/6 + 2

                    = 19/6 m

New breadth = 3/2 + 2

                      = 7/2 m

New Area = 19/6 * 7/2

                 = 133/12

New perimeter of the rectangular garden = 2 ( 19/6 + 7/2 ) m

                                                                      = 40/3 m

The cost of 1 m of barbed wire = 120

The cost of 40/3 m of barbed wire = 120 * 40/3

                                                          = 1600
