Question

a rectangular park is 45 m long nd 30 m wide . a path 2.5 m wide is construted outside tyr path . Find the area of the path​

Answer 1

Length of rectangular park = 45m

Breadth = 30m

Area = l ×b

==> 45×30

=> 1350 m²

Length of park along with path = 45+2.5×2

=> 45+5

=> 50 m

Breadth of park along with path =

30+2.5×2

=> 30+5

=> 35 m

Area of park along with path = L × B

=> 50×35

=> 1750 m²

Area of path = (1750-1350)m²

=> 400m²

Area of path is 400 m².

Answer 2

Now as we know,

area of path is  area of park with path - area of rectangular park                      

area of park =l x b= 45 x 30=1350 cm sq

area of park with path is =45+2.5+2.5 x 30+2.5+2.5 = 1750cm sq

area of path = 1750-1350=400 cm sq

therefore, the area of the park = 400 cm sq

pls mark as brainliest answer....
