Answer 2

Step-by-step explanation:

$\huge{ \fbox{given}} \\ perimeter \: = \: \frac{45}{7} \\ length = \frac{2}{7} \\ \\ - - - - - - - - - - - \\ perimeter = 2(length + breath) \\ = 2( \frac{45}{7} + \frac{2}{7} ) \\ = 2( \frac{47}{7} ) \\ = \frac{94}{7} \\ - - - - - - - - - - - \\ \sf \: extra \: knowlege \\ perimeter \: of \: a \: rectangle = 2(length + breath)$
