There are two trapezoidal experimental fields with the same area. The upper base of one is 20m long, the lower base is twice as long as the upper base, and the height is 55m. The upper base of the other is also 20m, and the lower base is 55m long. How many meters is the height?
有两块面积相等的梯形实验田，一块上底边长20m，下底是上底的2倍，高55m，另一块上底边也是20m，下底边长是55，高是多少米？
