Answer 1

Answer 2

Let h be the distance or height , a & b the parallel sides.

Then area of trapezium = 850
  1/2 (a+b)h               = 850
   (64 + b) x 17          = 850 x 2
      64 + b          =  1700/17
      64 + b     = 100
        b   = 100 - 64
        b  = 36 cm
Therefore, the other parallel side is 36 cm
