Answer:

A = 90

Step-by-step explanation:

We need to find the length of the base

Let EF be the base

length = change in x  (since the y's are the same value)

           = (9--9) = (9+9) = 18

Now we need to find the height  (change in y values)

-7 --2

-7 +2 = -5

But the value is positive because we are finding the distance  

height is 5 units

A = bh

A = 18*5

A = 90
