Answer: 28.5 square units
Step-by-step explanation: Count the whole squares in the figure then figure the areas of the triangular areas around the sides. Whole squares 3+5+5+5 = 18
Left side: 5/2 = 2.5
Top (2)( 3/2) = 3
Right: 4/2= 2
Bottom 6/2 = 3
Sum of triangular areas: 10.5
Add squares and triangles:
18+10.5= 28.5
It may be possible to compute the area by using the Pythagorean Theorem to get the lengths of the bases and height, but that's a bit more complicated!
