Extracted text: If f(x,y) = 200(y + 4) represents the "population density" of a planar region on Earth, where x and y are measured in miles, find the number of people in the region bounded by the curves x = and x = 4y -y. %3D Express the number of people in the region as an iterated integral. dx dy Evaluate the integral in the previous step. The exact value of the integral is Approximate the answer in the previous step and choose the correct units. The number of people in the region is approximately |реople (Round to the nearest integer as needed.)
