Answer 2

Let x = the length of the sides

Area = side * side = x * x = x^2

If we increase the length of the sides by 50%

1.5x = the length of the sides

Area = side * side = 1.5x * 1.5x = 2.25x^2

Increase in area is 225% - 100% = 125%

Increasing the sides of a square by 50% increases the area of the square by 125%.
