So if we want to find the area of this ellipse, and we're told that the area of an ellipse is a times b times pi, well then we would need to know what a is and also what b is.
00:21
And when you think about area, think about how area always looks.
00:27
Is it ever a negative number? no.
00:31
So we're always going to think about positive a and the positive version.
00:35
Of b.
00:35
We're not going to be adding and subtracting any number.
00:39
So there's no negative version that we need to think about.
00:43
But we do want to find a and b.
00:45
And so our larger denominator, since this is already in standard form, is going to be our 16.
00:52
And so since our 16 is the larger one, that's going to be the one that we associate with the a squared...
