Answer:
B, 30 inches
Explanation:
the areao of a parallelogram's formula is A = bh
in the word problem, we are given A and b, so we plug that into the formula to solve for h
450 = 15h < divide both sides by 15 to get h alone
450/15 = 30
15h/15 = h
h = 30
the solution to the word problem is B, 30 inches
