Diana has available 520 yards of fencing and wishes to enclose a rectangular area.
(a) Express the area A of the rectangle as a function of the width W of the rectangle.
(b) For what value of W has the area largest?
(c) What is the maximum area?
b). The area is largest at the point where its derivative is zero.
now differentiating area with respect to w, we get
Hence, area is largest when the...
