Please help me answer this question

Suppose that you are given two quantities, say x and y, that are both changing in time and that are related by some equation. A "related rates" problem is a problem in which we know the rate of change of one of the two quantities (say dx/dt ) at a certain time, and we want to find the rate of change of the other quantity (say dy/dt ) at this particular time. Consider for example the area of a square A = /2, where / is the length of its side. Suppose that at a particular moment in time, the length of its side is 3 meters, and that it is increasing at a rate of 2 meters per second. At what rate is the area of the square increasing at that particular time? (Enter your answer in square meters per second -- you only need to enter the number, not the units.) Answer: Check
