Answer:

[tex]A(x)=2x^3+16x^2+30x[/tex]

Step-by-step explanation:

we know that

The area of rectangle is equal to

[tex]A=bh[/tex]

where

b is the base of rectangle or width

h is the height of rectangle

we have

[tex]b=(x^2+8x+15)\ units\\h=2x\ units[/tex]

substitute the values

[tex]A(x)=(x^2+8x+15)(2x)\\\\A(x)=(2x^3+16x^2+30x)\ units^2[/tex]
