Answer:
20 cm² & 80 cm²
Step-by-step explanation:
Ratio of areas = (ratio of sides)²
Ratio of sides: 2/4 = ½
Ratio of areas: (½)² = ¼
Areas are:

1.584 and I believe that you can round that yourself
Let x be the original position.
After the first play they gain 9 yards. The position can be represented by
x + 9
After the second play they lose 22 yards. The position can be represented by
x + 9 - 22 = x - 13
Therefore, in total they lost 13 yards.
