**MathMate**, Thursday, May 26, 2011 at 4:19pmSubdivide the area into n vertical rectangles, each of width

w=(3-0)/n.

The (x-)position of the ith rectangle is x(i)=(i-1)(3/n)=3(i-1)/n.

The height is

h(i)=10x(i)+8

The area is

a(i)=w*h(i)

The total area is therefore A

n

∑ a(i)

i=1

Evaluate the summation and calculate the area A by taking limit n → ∞.
