C is right. She has partially completed the construction. Her next step is to use the arc markings to determine the radius to construct the circle.
Let the width be x, then the length is 2x
2(x + 4 + 2x + 4) = 46
(3x + 8) = 46/2 = 23
3x = 23 - 8 = 15
x = 15/3 = 5 ft
Therefore, width is 5 feet and length is 2(5) = 10 feet
