Answer 1

Step-by-step explanation:

when 3 is subtracted from length and bradth..t

then,perimeter will be

2(L-3+B-3)= 24

=2(L+B -9)= 24

it will help you...

Answer 2

Step-by-step explanation:

let the original length is x

breath is y

according to the question ,

2{(x-3)+(y-3)}=24

=>2{x+y -6 } =24

=> 2(x+y) -12 = 24

=> 2(x+y) = 24+12

=> 2 (x+y) = 36

=>(x+y) =18
