The length of the top surface is given by h(x) = 11x + 1.
Area is the amount of space occupied by a two dimensional object or figure. The area (A) of a rectangle is given by:
A = length * width
Let h(x) represent the width, hence:
66x² + 17x + 1 = (6x + 1)(11x + 1)
Since the width is g(x) = 6x + 1, hence the length = 11x + 1
The length of the top surface is given by h(x) = 11x + 1.
