Read Solution (Total 4)

Let us assume the initial area as 100m^2, so each side=10m
now, if area is increased by 69%, new area is 169m^2, so new side has = 13m
diff is (13-19=3cm), = 3/10 * 100 = 30% increase in side

let the area of sqare be a^2 and it is incresed by 69% so,
the area of sqare a^2=169/100=>a=13/10i.e, the side is increased by 130%
