This statement is false. If she bought 144 rolls of toilet paper to last the entire year, and there are 12 months in a year, then that would be 12 rolls of toilet paper a month.
For this case, the first thing we should do is use the following equation:

We have then:
(20) ^ 2 + (20) -30 = 390 m ^ 2
Answer:
the area of the land when the length of the dentist's office is 20 meters is:
390 m ^ 2
