Explanation:
Area of triangle =
(b*h)
Area of rectangle = b*h



Since there are two big triangles, then we can multiply 11.5 by 2.
11.5 * 2 = 23



Since there are two small triangles, then we can multiply 2 by 2.
2 * 2 = 4


Now, we can add up all of the areas so we can find the total area of the entire shape.
23 + 4 + 8 = 35
So, the area of the entire shape is 35 square cm.
