Answer 2

SoLuTiOn:-

Given

$</u><u>Perimeter\</u><u>:</u><u>of</u><u> </u><u>\</u><u>:</u><u> rectangle</u><u> = 15 \frac{3}{7} = \frac{108}{7} m \\ </u><u>L</u><u>ength \:</u><u>of</u><u> </u><u>\</u><u>:</u><u> </u><u>recta</u><u>ngle</u><u> = 4 \frac{2}{7} = \frac{30}{7} </u><u>m</u><u>$

We know that

Perimeter of rectangle = 2 (l + b )

So,

$\implies \frac{108}{7} = 2( \frac{30}{7} + b) \\ \\ \implies \frac{108}{7} = 2( \frac{30 + 7b}{7} ) \\ \\ \implies \frac{108}{7} = \frac{60 + 14b}{7} \\ \\ \implies108 = 60 + 14b \\ \\ \implies108 - 60 = 14b \\ \\ \implies48 = 14b \\ \\ \implies \: b = \frac{48}{14} \\ \\ \implies \: b = \frac{24}{7} \\ \\ \implies \: b = 3 \frac{3}{7}$

Therefore ,

${\purple{\boxed{\large{\bold{Breadth \: of \: rectangle \: = 3 \frac{3}{7} \: m}}}}}$
