Answer:
626.7 
Step-by-step explanation:
Consider the figure as a circle with radius 7.5 and a rectangle with width 30 and length 15.
CIRCLE
A = pi*r*r = pi*7.5*7.5 = 56.25pi =176.7
RECTANGLE
A = l*w = 15*30 = 450
176.7 + 450 = 626.7 
You need to explain to us what to do or else nobody will understand what your trying to ask for.
Had to look for the missing options and here is my answer.
Given that the market value of the house is $67,170 and it has a 49 percent assessment rate, the assessed valuation of this house would be $32,913. So how we got this amount is that we multiplied 0.49 by 67,170 and we got 32,913.3. Hope this answers your question.
