PERIMETER
==============================
Solve:
[tex] \implies\sf \large P=2l+2w[/tex]
[tex] \implies\sf P=2( {x}^{2} + 2x - 3) +2(5x + 4)[/tex]
[tex] \implies\sf P=(2 {x}^{2} + 4x - 6) +(10x + 8)[/tex]
[tex] \: [/tex]
[tex] \LARGE \begin{align} \sf\pink{2 {x}^{2} } \blue{ + \: \: 4x} \red{ - 6} \\ \sf \underline{+ \: \: \: \: \: \: \: \: \: \: \: \blue{10x} \red{ + 8}} \\ \sf \pink{2 {x}^{2}} \blue{ + 14x} \red{ + 2} \end{align}[/tex]
Final Answer:
[tex] \sf \huge \orange{ P={2x}^{2} + 14x + 2}[/tex]
