Best ResponseYou've already chosen the best response.0Area = LW; L=W+2 63 = (W+2)(W) 63 = W^2 + 2W W^2 +W  63 = 0 so far so good?

Best ResponseYou've already chosen the best response.0the quad formula is: (middle) + sqrt(middle^2  (4)(first)(last))  2(first) Lets plug it in :)

Best ResponseYou've already chosen the best response.0we actually get 2 answers, but we can throw out the negative because area is not a negative measurement

Best ResponseYou've already chosen the best response.0L = W+2 so about 9.45 if I did it right :)

Best ResponseYou've already chosen the best response.0becuase I chopped off alot of decimals, we get a skewed result. but its close

Best ResponseYou've already chosen the best response.0so what does the final answer look like

amistre64

Best ResponseYou've already chosen the best response.0itll probably include a radical sign for an eexat nswer; but the best I can do with an estimate is: W=about 7.45 and L=about 9.45

Best ResponseYou've already chosen the best response.0i dunno, my computer is slowing down something feirce. try it in another question post; and ill see what i can do

Best ResponseYou've already chosen the best response.0I know...iknow..... i see where I messed up. A=63; L=9 and W=7 i lost a "2" in the equation somewhere lol... w^2 +[2]w 63 = 0 <THAT ONE!! 2/2 + sqrt(4  (4)(1)(63))/2 1 + sqrt([252] +4)/2 <AND I forgot how to multiply 1 + sqrt(256)/2 1 + 16/2 1 + 8 W = 7 L= W+2 = 7+2 = 9 Area = 9(7) = 63 Are ya happy now :)
