+231 A TV screen measures 24 by 16 inches. If each dimension is increased by 20%, by what percent is the area increased?
+934 If each dimension is increased by 20% that is a 1.2*1.2= 1.44= 44% area increase.

We can assign the length and width variables, l and w respectively.
The increase in each dimension would result in:
(l*1.2) * (w*1.2) = lw * 1.44
Since we know that lw is the original area, there is a 44 percent increase.
We don't even need to consider the fact that the dimensions are 24 and 16!
