    Circumference of stitching = S = 2x + 2y + π x
    Now S = 100 Thus 2x + 2y + π x = 100 that gives y = 50 x - π/2 x
    Area A = 2xy + 1/2 π x^2 where y = 50 x - π/2 x

    I would just like to raise a concern in that how awful the clarity of worded problems are becoming nowadays (this one just adds to all the others I've seen). Should it not read perimeter of stitching?

    However, this may be HenryMerrild's translation of the problem from a Norwegian original.
