Answer:
171 Square Feet
Step-by-step explanation:
We first cut the figure up into smaller parts...
we then use the formula (L x W = A) to find the area
L = Lenth
W = Width
the first rectangle (1)...
15 x 5 = 75
the second figure (2)...
8 x 9 = 72
the third figure (3)...
6 x 4 = 24
now we have to add up all the values to find the area of the entire figure...
75 + 72 + 24 = 171

Distance from finish line can be computed by subtracting the amount he has ran from 3. Every minute he runs .5km, and we can use this to create a function to describe this instance.

The distance remaining is equivalent to the minutes multiplied by .5km for each minute subtracted from 3 which is the total distance.
