Find the surface area of this right triangle

Answer:
144 square centimeters
Step-by-step explanation:
So the first triangle, which is on the side. We do 3 x 4, which is 12. We would normally divide it by 2 since it is a triangle, but since there is 2 triangles that are the same, we keep it 12. Next, we have the bottom rectangle. We do 4 x 11, which is 44. Next we do the top rectangle, 5 x 11, which is 55. Next we do the side rectangle, 3 x 11, which is 33.
Next we add all of these answers together!
12 + 44 = 56
56 + 55 = 111
111 + 33 = 144
ANSWER: 144 square cm
