The length L of a rectangle is decreasing at the rate of 2cm/sec while the width w is increasing at the ate of 2 cm/sec. When L= 12cm and w=5cm, find the rates of change of the area.

Question

mathmale · Answer

what have you done so far?  Why not draw a rectangle and label the length and width L and w respectively?

this is a static illustration:  nothing moves, nothing changes.

How do you introduce rates of change when you bein with A = wL?
