Answer:

(A)

Explanation:

Let y be the length of the rectangular backyard and then according to the question, y should be atleast 150 ft, then the possible inequality is:

$y\geq150$

and the distance around should be no more than 450ft, then the possible inequality is:

$2x+2y\leq450$

Then, the shaded region (green) is the possible dimensions of the backyard.
