Question

Rectangles beneath a line
a. A rectangle is constructed with one side on the positive x-axis,
one side on the positive y-axis, and the vertex opposite the ori-
gin on the line y = 10 - 2x. What dimensions maximize the
area of the rectangle? What is the maximum area?
b. Is it possible to construct a rectangle with a greater area than
that found in part (a) by placing one side of the rectangle on
the line y = 10 - 2x and the two vertices not on that line on
the positive x- and y-axes? Find the dimensions of the rect-
angle of maximum area that can be constructed in this way
