It is easier to understand when to pull you.
Start by drawing a rectangle 9 by 6th
Now draw a rectangle around the same width on each side. Seal the gap between the sides of the rectangle, the primary and X. The length of the outer rectangle is 9 x 2 and the width is 6 x 2
Now the area of the rectangle outside the track (path + flower is) is (9 x 2) (6 x 2)
We only want the area to the total area minus the area of flower beds (9 * 6), then map
(2x +9) (2x 6) -54 = 100
4x ^ 2 + 12x 18 x -54 = 100
4x ^ 2 + 30x -154 = 0
2x ^ 2 15 x -77 = 0
(2x -7) (x 11) = 0
Since we have a positive field width, the street is 7 / 2 = 3.5 m wide
