Area = 99 = length * width = length * 11
Length = 99 / 11 = 9 units
Use the Pythagorean theorem.
Hypotenuse = √(9*9 + 11*11)
= √ ( 81 + 121)
= √ ( 202 )
≈ 14.2 units
rounded to 1 decimal place.

I read the problem wrong. I thought one of the diagonals was 99, not the area. I will correct that now. Sorry!

Are you sure 14.2 is not the correct answer?

The width cannot be longer than the length (that is its meaning). Post should be reviewed for accuracy.

Here's what an independent third party has to say about length vs. width: "Yes, the width can be longer than the length depending on the context and orientation of the object. Conventionally, length is considered the longest dimension, but this is not a fixed rule. For example, when talking about screens (like your television or computer monitor), width is usually the longer side."
