Area of square = x^2
If length is multiplied by 3, then each side of square is now 3x
new Area = (3x)^2 = (3x)*(3x) = 9x^2
So the Area has increased by a factor of 9.
In general, the Area will always increase by a factor which is the square of the factor applied to the side length.
2x+2x+3x+3+3x+3=146
10x+6=146
10x=140
x=14
45 units is the longest side
