$\large\color{Yellow}{\colorbox{green}{\colorbox{crimson}{ ANSWER }}}$

(a) Length of fencing the park

= Perimeter of park

= 200+300+80+300+200+260

= 1000 + 340

= 1340 cm

∴$\boxed{Perimeter \; \; of \; \;park = \; \;1340 cm}$

(b) Total cost of fencing

= Rs. 20 × Perimeter of fencing

= Rs.20 × 1340

= Rs. 26,800

∴$\boxed{Total\; \; cost =\; \; Rs.26,800}$

(c) Perimeter of regular hexagon = 6 × side

(d) Perimeter of square garden

= 4 × side

= 4 × 5 cm

= 20 cm

∴$\boxed{Perimeter\; \; of \; \;garden = \; \;20 cm}$

Answer 2

$(a) Length \: of \: Fencing \: the \: \: \\ park = \: perimeter \: of \: park$

$=200+300+80+300+200+260$

$=1000+ 340$

$= 1340 \: cm$

$: perimeter \: of \: park =1340 \: cm$

$(b) Total \: cost \: of \: Fencing$

$= Rs. 20 × perimeter \: of \: Fencing$

$= Rs \: 20 × 1340$

$= Rs 26,800$

$Total Cost = 26,800$

$(c) Perimeter \: of \: Regular \: \\ Hexagon = 6×side$

$(d) \: perimeter \: of \: Square \: Garden :$

$= 4×side$

$= 4×5$

$=20$

$perimeter \: of \: Garden = 20 \: cm$
