So it's easier to calculate if you figure out how much time it took her to finish 25% of the wall. Since it took her 45 minutes to do 75%, it took her 15 minutes to do 25%. Then you just multiply.
Therefore, it takes her 60 minutes to finish building her wall.
3.866 microseconds? 7 x 522 nano seconds = 3.86600 ms

Answer:
388
Step-by-step explanation:
We need to find the area of the semicircle and parallelogram separately and then combine.
The formula for the area of a semicircle is 1/2(pi*r^2)
r = 12. 12^2 = 144
1/2(pi*144) = 226..1946711 which we can just round to 226
The formula for the area of a parallelogram is bh
b = 18, h = 9. 18*9 = 162.
226+162 = 388
