[15 points] compute ffr2(x + 1)y2 da, r = [ 0, 1] x [0,3), by riemann sum definition. you must use the riemann sum definition to receive credit.

Looks like the integral is

where . (The inclusion of will have no effect on the value of the integral.)

Let's split up into equally-sized rectangular subintervals, and use the bottom-left vertices of each rectangle to approximate the integral. The intervals will be partitioned as

and

where the bottom-left vertices of each rectangle are given by the sequence

with and . Then the Riemann sum is

c. (3,2,6) is the answer.

h= 12 inches
