<u>Answer:</u>
32 units
<u>Step-by-step explanation:</u>
We have a quadrilateral ABCD and we are given the following coordinates for these vertices:
A (-11,-6)
B (-3,0)
C (1,0)
D (1,-6)
AB =
= 10 units
BC =
= 4 units
CD =
= 6 units
AD =
= 12 units
Perimeter of ABCD =
= 32 units
Check the picture below.
you can pretty much count the units for the base and its height off the grid.
