Answer:
D. 17.4 yards
Explanation:
Since the area of the rectangle is 17.36 square yards, and the width is 3.1 yards, we set up and solve this equation to find the length:
17.36 = 3.1h, so h = 5.6 yards.
From this, the perimeter of the rectangle is 2(3.1 + 5.6) = 2(8.7) = 17.4 yards.
So D is the correct answer.
