Answered by bobpursley
area square=s^2
if doubled, area= (2s)^2=4s^2

percent= changeInArea/area * 100
= 400/1=four hundred percent

If the result is 400% of the original 100%, then the increase is 300%

+100% = doubled
+200% = tripled
+300% = quadrupled
Answered by Damon
That is always confusing and the thing to remember is that doubling is 100% increase.
