Answer:

4x^6+12x^5+8x^4

Step-by-step explanation:

Height of the rectangle=4x^3

Width of the rectangle =x^3+3x^2+2x

Area of a rectangle = Height X Width

=4x^3(x^3+3x^2+2x)\\=4x^3*x^3+4x^3*3x^2+4x^3*2x\\=4x^{3+3}+12x^{3+2}+8x^{3+1}\\=4x^6+12x^5+8x^4

The area of the entire rectangle is: 4x^6+12x^5+8x^4 in standard form.
