Answer 1

perimeter of rectangle

$24 \: cm$

length of rectangle

$= 2 \: \: cm$

formula ,

$p = 2(l + b) \\ \\ 24 = 2(2 + b) \\ \\ 24 = 4 + 2b \\ \\ 2b = 24 - 4 \\ \\ 2b = 20 \\ \\ b = \frac{20}{2} \\ \\ b = 10 \: cm.$

Answer 2

perimeter of rectangle = 24 cm

length of rectangle = 2 cm

formula ,

$\begin{gathered}p = 2(l + b) \\ \\ 24 = 2(2 + b) \\ \\ 24 = 4 + 2b \\ \\ 2b = 24 - 4 \\ \\ 2b = 20 \\ \\ b = \frac{20}{2} \\ \\ b = 10 \: cm.\end{gathered} </p><p>$
