  1. The slopes of the trapezoids and triangles do not match

    the slope of the trapezoids have a Rise/Run of 2/5

    the triangles have a rise/run of 3/8

    2/5= 0.4

    3/8=0.375

    this means that there is a tiny gap between shapes, resulting in about 1 unit

    x = 2 – ( 3×5)/8 = 0.125

    the area of triangles are = 2x ( 5 x 0.125)/2 = 0.625

    the are of parallelogram is = 3 x 0.125 = 0.375

    the toal missing space is = 0.625+ 0.325 = 1

    and thats 64 + 1(which is missing area) = 65

    Yea im not that smart …
