The area of the entire square is 49. The area of the white part would be
49pi/4 because the radius is 7 so, then you put in the area of a circle formula. After that it looks like the circle is in fourths so 49pi divided by 4.


The answer to this question is 49 - (49pi/4)

Or it can be 56 - (49pi/4) because it looks like it is not a square and it is 7cm + 1cm and so that = 8cm so the are for that would be 56.

Good catch. This is not a square. You can tell by looking at quarter circle's radius, which is equal to the height of the rectangle but shorter than its base.
