Problem 13.1. Let $(t) = t´ and A(z) = 5 * ** = tadt. Xx+h (e) We are going to use a single rectangle that roughly overlaps the shaded region. The base of this rectangle should be on the interval 2 st 5x+h. Draw a rectangle overlapping with the shaded region. (f) What is the length of the base of this rectangle? (g) What is the height of this rectangle? (There are several reasonable answers for what the height of the rectangle should be. Your answer will involve x and may or may not involve h, as well.) (h) Write a formula for the area of your rectangle.
