A company is expanding its building area from 14,000 square feet to 19,880 square feet. What is the percentage increase of the area of the building space?
I remember I had a lot of trouble with this in geometry! This is a matter of ratios and division. You can grab a calculator and divide 19,880 by 14,000 (because the building increased, and you’re seeing how much bigger it is than the original). We can also do it by hand...
19880/14000 1988/1400 (divide by 10) 994/700 (divide by 2) 142/100 (divide by 7) 142% is your answer. The 100% implies you made another building, so the real answer is that the building size increased by 42% (since you already have the 14000 sqft building)
