Answer:
C) 18 square units
Step-by-step explanation:
There are many ways to go about solving this. You could divide it into two triangles with a middle section. But it might be easier just to count the squares:
whole squares = 12
half squares = 4 (which equals 2)
3/4 square = 4
1/4 squares = 4
(add the 3/4 and 1/4 squares to equal 4)
12+2+4=18
