area of trapezoid = (base + other base)/2 * (height)

224 = (x + 20)/2 * 16
28 = x + 20

x = 8m

            Again, @CubeyThePenguin  "solves"  the problems even without reading their descriptions.

            I must go to fix after him / (her) 


    %28%2820%2Bx%29%2F2%29%2A16 = 224


    20 + x = %28224%2A2%29%2F16 = 28


      x    = 28 - 20 = 8.


ANSWER.  the length of the other base is 8 meters.

Solved.
