Answer:
p + 2
Step-by-step explanation:
[tex]A=lb \\ \\ \implies \: b = \frac{A}{l} \\ \\ \implies \: b = \frac{p(4 {p}^{2} - 16) }{4p(p - 2)} \\ \\ \implies \: b = \frac{4p({p}^{2} - 4) }{4p(p - 2)} \\ \\ \implies \: b = \frac{4p({p}^{2} - {(2)}^{2} ) }{4p(p - 2)} \\ \\ \implies \: b = \frac{\cancel{4p({p} - {(2)})}({p} + {(2)}) }{\cancel{4p(p - 2)}}\\ \\ \implies \huge \orange{ \: b =(p + 2)}[/tex]
