Question

want answer in proper solution​

Answer 1

Answer: 400 m²

Step-by-step explanation:

l of park = 45 m

b of park = 30 m

Area = l × b

        = 45 × 30

        = 1350 m²

Area of park with path = l of park + b of path + b of path × b of park + b of path + b of path

                                     = 45 + 2.5 + 2.5 × 30 + 2.5 + 2.5

                                     = 50 × 35

                                     = 1750 m²

Area of path = Area of park with path - Area of park

                     = 1750 - 1350

                     = 400 m²

Thus, area of the park = 400 m²

Hope it helps...

Answer 2

Answer:

Area of park=l×b

45×30=1350cm²

Area of park with path is

=45+2.5+2.5×30+2.5+2.5

=1750cm²

Therefore,

Area of path=

Area of park with path - Area of rectangular park

=1750-1350

=400cm²
