Step-by-step explanation:

$Given , perimeter \: of \: rectangle = 230cm$

$and, \: length \: of \: rectangle ,L = 70cm$

$let, the \: breadth \: of \: the \: rectangle \: be \: B.$

$perimeter \: of \: rectangle = 2(L+B)$

$= 2(70+B) = 230$

$= 70+B = \frac{230}{2}$

$= 70+B = 115$

$= B = 115-70$

$= B = 45cm$

$Now, area \: of \: rectangle = L×B$

$= 70×45cm²$

$= 3150cm².$

$therefore, \: the \: breadth \: and \: area \\ \: of \: rectangle \: are \\ 45cm , \: 3150cm² \: respectively.$
