Answer 1

Heya..

Since cost of fencing a rectangular Park at ₹14.60 = ₹1606

=) Cost of fencing a rectangular Park = Cost per metre * Perimeter of rectanglular field = ₹1606

=) ₹14.6 * Perimeter of rectangular Park = ₹1606

=) Perimeter of rectangular Park = ₹1606/₹14.60

=) P = 110 m

=) Perimeter of rectangle = 2(l+b)

=) 2(l +23) = 110m

=) 2l + 46m = 110m

=) 2l = 64m

=) l = 64/2 = 32m.

Hope it's helpful to u.
