The aswer to the puzzle is circle which you get area for by doing ((40/pi/2)^2)Xpi=126.7276768 meter sqaures
The aswer for the second puzzle is a semicircle which you can find the are of by doing (((80/(2pi0))^2)Xpi)/2=254.65537 meter sqaures
For the third puzzle I have had difficulty so I asumed that couln't have curves and the answer was 180 metere sqaures.
