Question 203764
<font face="Garamond" size="+2">


If the pool is square and the border is uniformly 1 foot wide all the way around, then the side length of the outside edge of the border must be *[tex \Large p + 2]


The overall area must then be *[tex \Large (p + 2)^2 = 400]


Solve for *[tex \Large p] (exclude the negative root) and *[tex \Large p^2]
