I'LL GIVE BRAINLIEST:

Answer:
The answer is C:120 square cm
Step-by-step explanation:
The ratio is 1 to 3.
This shows that the second rectangle is three times larger than the smaller one.
To figure out the area of the second rectangle you multiply the first rectangle's area by 3.
This is 40x3=120.
So your answer is 120 square cm
