As the zoom lens in a camera moves in and out, the size of the rectangular image changes. Assume that the current image is 4 cm × 3 cm. Find the rate at which the area of the image is changing (dA/df) if the length of the image is changing at 0.6 cm/s and the width of the image is changing at 0.2 cm/s. ▸ 5.2 cm2/sec ▸ 6.0 cm2/sec ▸ 3.0 cm2/sec ▸ 2.6 cm2/sec Title: As the zoom lens in a camera moves in and out, the size of the rectangular image changes.
