You can put this solution on YOUR website! 3) you are dealing with exponential growth, the area of a rectangle is squared.
So, a rectangle 4 wide x 6 long = 24 square (meters, inches, whatever)
If you grow by 50%: 4 + 0.5(4) = 6 and the length grows to 9, and 6 x 9 = 54. The original area is 24/54 = 44% of the new area
The new area is 54/24 = 225% of the old area
