Answer: 30 square inches
This is the same as writing [tex]30 \text{ in}^2[/tex]
===========================================================
Reason:
You could use the shortcut formula the other person mentioned.
Or you could break the figure into two triangles and a rectangle between them.
A = area of the triangle on the left
A = base*height/2
A = 3*4/2
A = 6
B = area of the rectangle in the middle
B = base*height
B = 5*4
B = 20
C = area of the triangle on the right side
C = base*height/2
C = 2*4/2
C = 4
Add up those sub-areas to get the grand total area
A+B+C = 6+20+4 = 30 square inches
