    B

    Step-by-step explanation:

    split the triangle in to 5 different shapes

    3 of them are rectangles, and 2 are triangles

    all of the rectangles are the same size being:

    12 by 5 so 12 times 5. then do this 3 times for each rectangle.

    Now take the triangles and find the area for those.

    which is 1/2 or base times height. so half of 5 multiplied by height (4.3)

    being 2.5 times 4.3 giving you 10.75

    now take the area of the rectangles and triangles and add them together

    60+60+60+10.75+10.75 = 201.5 ft2
