b=3l/4
lb=192
3l²/4=192
3l²=768
l²=768/3
l=√256=16
b=3*16/4=12
perimeter=2(l+b)
=2(28)
=56

let length be X
then breadth= 3x/4
area of rectangle = length X breadth
192meter.sq = X*3x/4
= 3x²/4
192* 4= 3x²
768=3x²
768/3= x²
156= x²
√256=√x²
16= X
therefore length = x = 16,
breadth=3x/4= 16*3/4
= 48/4
= 12
perimeter= 2( length+ breadth)
= 2(16+12)
= 2(28)
= 56.
since it is hopeful answer if you have any doubts remain me
