Step-by-step explanation:

$let, the \: breadth \: \\ of \: rectangle \: be \: b \:$

$and \: length \: be \: L.$

$According \: to \: ques:$

$b = \frac{3}{4} L$

$perimeter = 84$

$perimeter \: of \: rectangle = 2(b+l)$

$2(L+ \frac{3}{4} L) = 84$

$= \frac{3}{4} L +L = 42$

$= \frac{3L + 4L}{4} = 42$

$= 7L = 168$

$= L= 24$

$now ,$

$b = \frac{3}{4} L$

$b = \frac{3}{4} ×24$

$b = 18$

$therefore , the \: breadth \: \\ and \: length \: of \: rectangle \: are \\ 18cm \: and \: 24cm \: respectively.$
