I think maybe A Im not 100% sure tho
It would travel 65 times 4 = 260 miles
T could be located at 15 because 5 plus 15 equals 20
Since you have an angle and at least one side you can use either sine, cosine or tan. For this question, you would use sine like above. Hope this helps!
Area of box : 18*18, which is 324
area of larger triangle : 18*16/2 which is 144
area of larger triangle : 8*16/2 which is 64
add them all to get 532
