Terminology for area's

Terminology for area's

Terminology for area's

Listen to this,

If I say I have something that is "3 ft^2" (read: three feet squared), does that mean I'm talking about a square that is 3 by 3 or a square with sides that have an area that adds up to be 3?


If I say I have something that is "3 square feet" (read: three square feet), does that mean I'm talking about a square that is 3 by 3 or a square with sides that have an area that adds up to be 3?

I guess my basic question is, "Is there a difference between 'three feet squared' and 'three square feet'; and if so what is it?


RE: Terminology for area's

There is no difference to my knowledge.

RE: Terminology for area's

the way i was taught was 3' sq. equals 3'x3' or 9 sq feet while 3 sq ft equals 12x12 3 times
i hope i am not adding to the confusion

RE: Terminology for area's

I have found an answer from someone else which I've made up my mind to believe because he was able to back it up with a website.  

Here is my question posted on another forum, and the answer that I favor.
