Answer:

4x² +100x

Step-by-step explanation:

The total area of the garden plus the pine bark border is given by:

$A = (30+2x)*(20+2x) = 600+60x +40x +4x^2$

The area of the garden alone, without the border, is:

$A_G = 30*20=600$

Subtracting the total area by the area of the garden gives us the area of the border:

$A_B = A -A_G\\A_B= 600+100x+4x^2 - 600\\A_B = 4x^2 +100x$

The total area of the border is described by 4x² +100x.
