8. A racetrack has inside and outsides as shown below. The racetrack itself is 3 meters wide. How many square meters of land does JUST the racetrack take up? (Find the area of the shaded region.) Round to the nearest whole number.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
