Alternative Answer

We know it is 16:9. So we know that 16 is the length and 9 is the height. Ben gave us height, which is 4. Now, we must find the length. To do this, we do this:

16/9 * x/4

If you look at the equation, you will see that the height is 9 on the left, and 4 on the right. We know that the length is supposed to be 16, but we donโ€™t know what it should be if the HEIGHT is to be 4. And so, we place an โ€˜xโ€™.

By cross multiplying, we end up with x = 4(16)/9
Which gives us 7.11 :slight_smile:

Hope that helps :slight_smile:
