So I'll have this triangular section up here. So I have this triangular section. I could just think about this as a trapezoid, but I'm just going to split it up into a triangle and a rectangle. And then I have this section right over here in green. So what is the area of this entire thing? Well, the area right over here, we have 20 gallons per minute. So 20, oh sorry, not 20 gallons per minute, 20 minutes times two gallons per minute, two gallons per minute times 1 1⁄2.
