<PRE><B>Question 823250</B>
---
original area:
a = Lw
---
scale factor:
s = 1+1/3 = 4/3
---
scaled area:
A = sL*sw
A = ss*Lw
---
percent increase in area:
p = A/a * 100
p = ss*Lw/Lw * 100
p = ss * 100
p = (4/3)^2 * 100
p = 177.777777
---
answer:
p ~= 177.8% increase in area
in other words, not quite a doubling of the area
note that the original dimensions of the picture do not matter at all in this calculation
