A company is expanding its building area from 12,000 square feet to 16,080 square feet. What is the percentage increase of the area of the building space?

To find the percentage increase, we need to calculate the difference between the new and old area, divide that by the old area, and then multiply by 100 to express it as a percentage:

Increase in area = 16,080 sq ft - 12,000 sq ft = 4,080 sq ft
Percentage increase = (4,080 sq ft / 12,000 sq ft) x 100% ≈ 34%

Therefore, the area of the building space has increased by approximately 34%.
