Answer 2

$solution :$

$= = = = = = = = = = = = = = = = = = = = = =$

$length \: = 23 \: cm \:$

$breadth = \: 19 \: cm$

$step \: - by - step$

$let \: breadth \: be \: x \: and \: legth \: be \: 4 + x$

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

$84 = 2(x + 4 + x)$

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

$42 = 2x + 4$

$2x = 42 - 4$

$2x = 38$

$x = \frac{38}{2}$

$x = 19$

$si \: if \: x \: means \: breadth \: is \: 19 \: . \: so \: length \:$

$4 + x \: will \: be \: 19 + 4 = 23$

$therefore \: length \: = 23$

$breadth \: = 19$

$= = = = = = = = = = = = = = = = = = = = = =$

$hope \: it \: helps \: u \: \\ pls \: mark \: me \: as \: brainliest$
