Answer 1

Answer:

The perimeter is 150 and the cost is ₹600

Step-by-step explanation:

here, Rectangular park length(l)= 45m

Rectangular park breadth(b)= 30m

perimeter of rectangle= 2(l+b)

perimeter of rectangular park= 2(45+30)

=150m.

Cost of fencing per meter is ₹40

then cost of fencing for rectangular park is =40×150

=₹600

Answer 2

Answer:

$l = 45m \\ b = 30m \\ perimeter \: of \: park = 2(l + b) \\ p = 2(45 + 30) \\ p = 2 \times 75 \\ p = 150 \\ \\ \\ cost \: of \: fencing = 40 \times 150 \\ = 6000 \\ \\ the \: cost \: offencing \: is \: 6000$
