For the answer to the question above, the area of a parallelogram is equal to one-half the height times the sum of the bases. We already know the area (276) and the sum of the bases (46). So make an equation and then add in what we know:

A = (½H)*(Sum of the bases)
276 = (½H)*46 divide each side by 46
6 = ½H then multiply each side by 2
12 = H
So the answer is
12cm.
