Answer:
[tex]A = 3p^5+p^3+12p^2+4[/tex]
Step-by-step explanation:
We are given the following in the question:
Length of rectangle = [tex]3p^2+1[/tex]
Width of rectangle = [tex]p^3+4[/tex]
Area of rectangle =
[tex]A = \text{Length}\times \text{Width}[/tex]
Putting values, we get,
[tex]A = (3p^2+1 )\times (p^3+4)\\A = 3p^5+12p^2+p^3+4\\A = 3p^5+p^3+12p^2+4[/tex]
is the required expression for area of triangle.
