Approximate the integral
f(x, y) dA by dividing the rectangle R with vertices (0, 0), (4, 0), (4, 2), and (0, 2) into eight equal squares and finding the sum
f(xj, Y;) AA;
where (x;, y;) is the center
i = 1
of the ith square. Evaluate the iterated integral and compare it with the approximation.

x²y dy dx
Step 1
The vertices of the rectangle are given as (0, 0), (4, 0), (4, 2), and (0, 2).
As the x-coordinate varies from 0 to 4, the length of the rectangle is
As the y-coordinate varies from 0 to 2, the breadth of the rectangle is
Therefore, the area of the rectangle is
