It's counter-productive to think of estimates as correct or incorrect since estimates, by definition, are not supposed to be correct but that way of thinking will seriously annoy your teacher. Here's what the teacher wants to hear: Fern's estimate is incorrect since she should have rounded 548 up to 550 and got 420. That estimate is closer to the actual difference. Fern is a tragically misguided girl.

Although there is a method similar to long division, it is rather difficult to explain. So the best ways are: Use a calculator. or Use trial and error to get a rough estimate and improve on it.
For accurate calculations, more information is needed. For a rough estimate, you can assume the field is approximately square, and take the square root of the area to get the length. Or you may want to assume a different side ratio - for example, 1.5:1 - and do the corresponding calculations. It won't make much difference if all you want is a rough estimate.
60 or 6.0 is the correct answer because you round 19.7 and 5.1 and then you add or subtract i subtracted but if you are adding then the answers is 160 your welcome! :D
