Answer: A=x²+6x+8
Step-by-step explanation:
Since we are looking to find the area of the entire rectangle, we would use the formula [tex]A=lw[/tex]. [tex]l[/tex] is length and [tex]w[/tex] is width. You would approach this problem like any other area of the rectangle problem, except you are dealing with polynomials instead.
[tex]A=(x+2)(x+4)[/tex]
[tex]A=x^2+4x+2x+8[/tex]
[tex]A=x^2+6x+8[/tex]
