Remember, a is the area of our triangle, and we're measuring everything in meters, as you can tell from the information they've given us. And so area is going to be in square units, and so it's going to be in square meters. Now the height at time t sub zero. Well, both the base and the height, those are lengths, they're gonna be measured in meters. And so our height at time t sub zero is going to be in meters. And then here we have the rate of change of our area with respect to time. So our area, we already know, is in meters squared.
