Answer:
The unit rate of change is of 
Step-by-step explanation:
We are given a set of points (x,y).
To find the unit rate of change, we take two points, and divide the change in y by the change in x.
Points (4,9) and (8,12)
Change in y: 12 - 9 = 3
Change in x: 8 - 4 = 4
Unit rate of change: 
46.059 is the faster time because it is a smaller number than 46.23 by 0.171
Width is 14 meters
14 doubled is 28-6 is 22
22+22+14+14=72
