Answer:
33 (units)
Explanation:
We can divide this into three parts. The rectangle, and the two triangles. Find the area of the rectangle (l*w, so 4*6, which is 24) and then find the area of the triangles (b*h/2, so 3*3/2, which is 4.5). Since there are two triangles, we can multiply the area of one triangle by two (4.5*2=9). Add up the area of each part (24 for the rectangle, 9 for the added triangles) and you get (24+9=33), which is your answer!
