Question 1141765
What is the area of a square that has a radius of 7(square root of 2) ft (from the center of the square to any vertex)?

49 ft^2
196 ft^2
147 ft^2
196(square root of 2) ft^2

The answer that I got was 49 ft^2. I was not sure how to solve this question, if it's possible to show steps on how it was solved. Thank You! 
<pre><b><u>My "TWO CENTS WORTH:"</b></u> I always associate RADIUS with a CURVE, namely a CIRCLE, but learnt something when Edwin pointed out that the term is also
                      used to describe a line segment from the center of a square to one of its vertices, and Alan further pointing out that that
                      describes any line segment from the CENTER of a regular POLYGON to any one of its vertices. The person also points this out. 
                      In this case, and with the polygon being a SQUARE, the radius can also be described as one-half the square's diagonal, in MY OPINION.
                      You learn something every day! At least I do!
