Answer:29119.66666...+14561.3333...=43681, 209ft^2, not square feet.Step-by-step explanation:"One side of a rectangle is 3 feet shorter than twice the other side find the sides if the area is 209 feet squared"Ok, so this is a tricky one- 209 feet squared, not 209 square feet, therefore the area is 209^2, or 43,681.Next, let's define our variables-x= the "other side"z= 3 feet shorter than twice sideWe can now make these (useful) equationsz=2x-343681= (2x-3)+xWe will focus on the latter for now-Simplify43681= (2x-3)+x43681= 2x-3+x43681= 3x-3+343684=3x/314561.3333...=xz=2x-3z=2*(14561.3333)-3z=29119.66666....29119.66666...+14561.3333...=43681
