The "width" of the rectangle would be the "circumference" of the tube whereas the length is merely the height of the tube.
.
Therefore, we have:
length = 11 inches
width = 2(pi)r = 2(3.14)(1.7) = 2(3.14)(1.7/2)
width = (3.14)(1.7)
.
area of rectangle = length * width
area of rectangle = 11(3.14)(1.7) = 58.718 square inches
