The region R is a rectangle with vertices P(a,lna), Q(a,0), S(3,0), and T(3,lna), where 1<a<3. I found that the expression for the area of the rectangle is f(a) = (ln(a))(3-a). The area of the rectangle is maximized for some c beween 1 and 3. Write the expression you ...

Multiply the area of the rectangle by the square of the scale factor to get the area of reduced rectangle. Reduced area = 720 * (1/6)^2 Reduced area = 720 * (1/36) Reduced area = 720/6 Reduced area = ? sq in.

**geometry**

A rectangle is easy, as it can be divided up into a grid WxL and the area is just WL Take a parallelogram ABCD with sides a and bases b. If you draw vertical altitudes at A and B, you will see a rectangle in the middle, a triangle sticking out on one end, and a triangle ...
