Area of Rectangle= Length * Widthsubstitute the area and the value of L in the formula 28,800 m^2= 2W * W 28,800= 2W^2divide both sides by 2 in an effort to isolate the variable w 14,400= W^2take the square root of both sides √14,400= W^2 we want the negative and positive root of the radicand (the number under the radical symbol - 14,400 in this case) 120= w OR -120= w
LENGTHL= 2W= 2(120)= 240 meters
ANSWER: The side lengths are W= 120 m; L= 240 m. Even though W= -120 too, it is not a valid solution in this case since a field cannot have a negative value.
