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. But we wanna know, this here, this is going to be the rate of change of our area with respect to time. So it's going to be an amount of area per unit time, and time here, we're using hours, as you can see from some of the information they've given us. So this is going to be area per unit time, or meters squared per hour.
