A thin wire 36cmlong formed into a rectangle if the width of this rectangle is 7cm.what is the length

${ \boxed{ \red{ \underline{ \blue{ \mathcal{ANSWER}}}}}}$

$Perimeter \: of \: the \: wire \:  =36cm\\2(l+b)=36\\⇒2[l+7]=36\\ ⇒2l+14= 36 \\ ⇒2l=36-14\\⇒l = \frac{22}{2} \\ ⇒l=11cm\\Hence, length =11cm$
