The ratio of width to length will be the same so
4/7 = 16/l
l = (7*16) / 4 = 7 * 4 = 28
length = 28 inches
The reason they have to be simplified is that you cannot add radical unless the number under the radical is the same on all of them.
For example:
If you add √8 + √32 without simplifying, the best you could do is an estimate. But if you're required to put your answer in standard radical form this would be an issue.
So, you would have to simplify to combine:
√4√2 + √16√2
2√2 + 4√2
6√2
