Calculus 1 (Related Rates) The length of a rectangle is increasing at the rate of 5 meters per minute, while the width is decreasing at the rate of 3 meters per minute. At a certain instant, the length is 20 meters and the width is 10 meters. At that instant determine (a) the rate of change of the area of the rectangle (b) the rate of change of the perimeter of the rectangle
