Answer:
A = 179.4 km^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 ( b1+b2) h where b1 and b2 are the lengths of the bases and h is the height
A =1/2 ( 7.6+20) * 13
A = 1/2 (27.6) 13
A = 179.4 km^2

Step-by-step explanation:
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (9, 2) and (x₂, y₂ ) = (9, - 5)
m = 
= 
Since division by zero is undefined then the slope is undefined.
This indicates that the line is vertical.
