Question

How long could the. Mural be if the length and height have to be whole numbers

Answer 1

The height has to be 4, 5, or 6, so the width would be 15, 12, and 10 respectively.
4*15=60
5*12=60
6*10=60
These are the only whole numbers between 4 and 6, as whole numbers are non-decimal numbers greater than or equal to 0
