This is a two tailed test
This is because of the ≠ sign in the alternative hypothesis which signifies that the rejection region in the alternative hypothesis are at the both sides of the hypothesized mean difference .

The decision rule is to reject the null hypothesis if z < - 1 . 64 and z > 1 . 64

Keep adding by the same value everytime so start with 10,000 then add 20,000 etc
Hey
Area of first rectangle = 18 x 21 = 378 in^2
Area of second rectangle = 17 x 9 = 153 in^2
Total area = 378+153 = 531 in^2
Option 1
Hope this helps :)
