/-3 /-3 /-3 divided everything by -3 to get y by its self
Y= 1/3 - 6 and that is you answer

Answer:
63,990 mi²
Step-by-step explanation:
We can find the answer by using the formula for the area of a trapezoid and putting in the given numbers.
A = (1/2)(b1 +b2)h . . . . where b1, b2 are the base lengths; h is the height
A = (1/2)(198 mi +276 mi)(270 mi)
A = 63,990 mi²
