I won't tell you the answer but I'll tell you how to do it
first, find the area of the rectangle (lxw)
Next, find area of the triangle (BxHx.5)
Then, subtract the area of the rectangle to the area of the triangle
7/3 written as a mixed fraction is 2 1/3
So
7/3 = 2 1/3
It’s b I did it I got it right
