the zero(s) of function 
is x=2
Step-by-step explanation:
We need to find the zero(s) of function algebraically.
We are given:
To find the zeros we put the function equal to zero.
So, the zero(s) of function is x=2

(Sorry I could only answer part A) The Answer is 84 -w-
We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56
