We know that the formula to find the area of a parallelogram is b*h, so in the first figure, we know that the base is 20cm and the area of 320cm^2. So the height is, 320/20=16. Now, we find the relationship between 20 and 25

 

20cm=25cm

16cm=?

1cm=25/20

16cm=25/20*16=20

So, the area is 25*20=\(\boxed{500}\)
