The length of a car park is 120 m longer than its width. The area of the car park is 6400 m^2.

a. How would you represent the width of the car park? How about its length? b. What equation represents the area of the car park? c. How would you use the equation representing the area of the car park in finding its length and width? d. What is the length of the car park? How about its width? Explain how you arrived at your answer. e. Suppose the area of the car park is doubled, would its length and width also double? Justify your answer.

Let w = w and l = w + 120
w(w+120) = 6400
W^2 + 120w -6400 =0
(w +160)(w-40) =0
w+160 =0 , w-40=0
w= -160 , w=40
Since there's no such negative value of width, our value for width is 40
l = w +120
l = 40 +120
l = 160 our length would be 160
Yes, if its area is doubled, the length and the width would be doubled also
