Find the area of quadrilateral ABCD in each case.
HElp PLEase ASAP

Let's see...

Step-by-step explanation:

*Note: we can't find the exact area of the shaded figure right off the bat, we have to find the area of a bigger figure and divide it by 2.

A = (0,0)

B' = (0,4)

C = (5,4)

D' = (5,0)

Note: the little [ ' ] next to the B and D indicate that it is not the same coordinate as B and D, just that those points would be the same as point B and D.

A =  l * w

A = 4 * 5

A = 20 units²

A = 20 ÷ 2

A = 10 units²

I hope this helps!
