Answer:

43 1/2

Step-by-step explanation:

The formula to find the area of a triangle is multiplying base times height divided by 2.

So we have 3+3+3 (which is the base) times height. Finally we have: 9 x 11, which is 99 and now we divide it by 2. So 99/2 = 49 1/2.

Now we subtract the missing rectangle, which we can find by multiplying 3 by 2, which is 6.

So now subtract 6 from 49 1/2, and you'll get 43 1/2.

Answer:

43.5

Step-by-step explanation:

(( I will be using "*" as a multiplication sign ))

Area of rectangle = length * width = 3 * 2 = 6

Area of triangle = 1/2 bh = 1/2(11*9) = 1/2 of 99 = 99 divided by 2 = 49.5

So, since we are taking away the rectangle from the triangle, we will subtract the area of the rectangle from the triangle.

49.5 - 6 = 43.5
