Thank you very much. I have one more question: The area of the heart is 20cm^2. If this is 72% of the area of the square, what is the area of the square?
Ms. Sue
What do you mean by the area of the heart?

Cecilia

The question is: The area of the heart (it's a picture of a heart inside a square) is 20cm^2. If this is 72% of the area of the square, what is the area of the square?
