Heyaa!!

We have

Length , l = 175 m

breadth , b = 125 m

p of rectangular park = l b

=> 2 ( l + b)

=} 2 ( 175 + 125)

=) 2 × 300

=) 600 m^2
it will be easy for u to know and keep this formula in ur mind absolutely this will help u to find out the cost / Area/ rate

cost = A × R

=} 600 × 12

=) ₹7200
