Question 177922: A rectangular pool measures 8m by 4m. A deck of unifrom width is to be built all the way around the pool such that the total area of the pool and deck will be 96m^2. Set up and solve a quadratic equation to determine the width of the deck.

the key is it is a uniform in width meaning the same all around the pool
:
so lets call this uniform distance x
:
so the length of the total area is 8+2x and the width is 4+2x. L=8+2x,W=4+2x
:

:
so x is either -8 or 2.....since lengths arent negative our answer is
:
x=2 meters
:
W=4+2x=8 meters
