You know that the area of a parallelogram is = bxh
There area of this parallelogram is 24 x 15 = you know that area of parallelogram is = b x h
Therefore are of this parallelogramgram is = 24 x 15 = 360
Now BC is also base for height DE
Therefore BC x DE = 360
18 x DE = 360
DE = 360 / 18 = 20
Therefore DE = 20
