​

Answer 1

Answer:

Cost of fencing for every 100 meters= ₹3800

Cost of fencing for every 1 meter= 3800/100

                                                        = ₹38

Cost of fencing for 450 meters= ₹38 x 450 = ₹17,100

Cost of fencing for 600 meters= ₹38 x 600 = ₹22,800

Cost of fencing of whole rectangle= 2(22800+17100)

                                                            = 2 x 39,900

                                                            = ₹79,800

Please follow me, I'd really appreciate! ^-^

Answer 2

Step-by-step explanation:

• perimeter of rectangle 2*( length + breath)
• So, 2*( 600+450)
• = 2*1050
• = 2100 meter

cost of 1 meter fencing= 3800÷100

= 38 rupees per meter

cost of fencing of rectangular field

= 2100*38

=79800 rupees
