best des
let,
the side length of the original square = 10.
Thus, the area of the original square = 100.
Since the area of the square increases by 69 percent,
the area of the new square = 169.
Thus, the side length of the new square = √169 = 13,
increase in the side length of the original square = (13 - 10)/10 * 100% = 30%
ans: 30%
