If the area of a square has increased by 60%, by what percentage has its side increased?

Submitted by: Administrator
answer, about 26%

square of 10cm by 10cm equal 100cm2
for it to increase by 60% then the new size is 160cm2
so each side would now be about 12.6cm by 12.6 cm
then each side went from 10 to 12.6cm for an increase of about 26%
