Considering the area of a square, we have that:
- The length of one side of the garage originally was of 17.9 ft.
- The length of one side of the garage now is of 21.9 ft.
- The percent increase in the length of one side was of 22.35%.
What is the area of a square?
The area of a square of side s is given by s squared, that is:
A = s².
The original area was of 320 ft², hence the original length was:
s² = 320
s = sqrt(320)
s = 17.9 ft.
The area increased by 50%, hence the new area is:
A = 1.5 x 320 = 480 ft².
The current length of one side is:
s² = 480
s = sqrt(480)
s = 21.9 ft.
The percent increase is the change divided by the initial length and multiplied by 100%, hence:
(21.9 - 17.9)/17.9 x 100% = 22.35%.
The percent increase in the length of one side was of 22.35%.
