I think the width is 13 and the length is 12
60 - 18 = 42
42/60 x 100 - 70%
To check this do 0.7 x 60 (which gets you 18, so it is right)
calculate length of the sides of the rectangle and multiply then do the same with the parallelogram
Total area is 51 square units
Answer:
x=2
Step-by-step explanation:

Add 14 to both sides
