C

Step-by-step explanation:

We need to find the area of BOTH the rectangle AND the triangle. So the formula to find area of a triangle is bh, or bh/2

b- base

h height

And obviously to find area of rectangles and stuff like that is just l x w

So let's find area of the rectangle, AKA the whole,

5x11=55

The area of the rectangle is 55

Now for the triangle,

The base is 5, and the height is 3. 5 x 3 = 15, and 15/2 = 7.5

The area of the triangle is 7.5

Now, subtract because we don't want the area of the triangle BUT the shaded region, so 55-7.5= 47.5 We have to add a unit so its 47.5^2, so the answer is C

Hope this helps!!
