Squaring 2-digit numbers--Why is this important?

What is the importance of knowing how to square two numbers?  Unless you are a full-time student, or an educator, you may be wondering why it is beneficial to know this information.  Certainly anyone working in landscaping, engineering, and construction-related fields knows the value of computing numbers quickly.  If you are a do-it-yourself type of person and own a home, there are many practical applications around the home, such as painting, flooring, and other remodeling jobs where quick calculations can save you time and money.

If you are installing ceramic tiles or hardwood flooring in your newly-remodeled kitchen or bathroom, and you know the dimensions of the room, you can purchase the right amount of supplies on your first trip to the home improvement store.  How unfortunate it would be if you miscalculated and purchased the wrong amount of a certain tile that was on clearance, and when you completed your job a few weeks later, you were unable to find additional matching tiles.
