Perimeter of rectangle is 48 inches area is 40 inches what are the length of the side
Aloiza [94]
\bf \textit{perimeter of a rectangle}=p=side+side+side+side&#10;\\\\&#10;or\implies p=w+w+l+l\implies p=2w+2l&#10;\\\\&#10;p=2(w+l)\qquad &#10;\begin{cases}&#10;w=width\\&#10;l=length\\&#10;------\\&#10;p=48&#10;\end{cases}\implies 40=2(w+l)\\\\&#10;-----------------------------\\\\&#10;\textit{area of it}=A=w\cdot l\qquad \begin{cases}&#10;w=width\\&#10;l=length\\&#10;------\\&#10;A=40&#10;\end{cases}\implies 40=wl\\\\&#10;-----------------------------\\\\

\bf thus\qquad &#10;\begin{cases}&#10;40=2(w+l)\to \frac{40}{2}=w+l\to\frac{40}{2}-l=\boxed{w}&#10;\\\\&#10;40=wl\\&#10;--------------\\&#10;40=\left( \boxed{\frac{40}{2}-l} \right)\cdot l&#10;\end{cases}

solve for "l" to find its length
