Answer 1

Answer:

-12$p^{3}$ + 28$p^{2}q^{2}$ + 8$p^{2}$ + 40pq

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

Let one side of rectangle be l and second be b.

Perimeter = 2*[(-6$p^{3}$+7$p^{2}q^{2}$+11pq) + (7$p^{2}q^{2}$ + 4$p^{2}$ + 9pq)]

= 2*(-6$p^{3}$ + 14$p^{2}q^{2}$ + 4$p^{2}$ + 20pq)

= -12$p^{3}$ + 28$p^{2}q^{2}$ + 8$p^{2}$ + 40pq Ans.
