And then the average height, the height here is 52, the height here is 44. So the average of 52 and 44, they are 8 apart, so then it's just going to be 4 from each of these, so it's 48. So the average height here is 48. And so 4 times 48 is 160 plus 32, so it's 192. And then finally, this last trapezoid, its base is only 1. Its base right over here is only 1. And then its height is 43 at the left side, 43 at the right side.
