Explanation:
this problem description is seemingly missing some information.
from what I think I understand, the outer dimensions of the parallelogram are 17 m and 10m, and what is needed is the size of h to the 10 m side.
the area of a parallelogram is
the length of one of the sides × the length of the height to this side.
so, we have here
150 = 10 × height
height = 150/10 = 15 m
