step 1
Find the area of the original parallelogram
A=bh
substtute the given values

step 2
Find the scale factor
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ----> scale factor
x ---> area of the dilated parallelogram
y ---> area of the original paeallelogram
so

we have

substitute

simplify

therefore

The scale factor applied was 1/2
