First find the area of the rectangle by multiplying the length and width of the rectangle, so 12 x25=300. Then find the area of the triangle, which is length x height/ 2. So 8 x 25=200/2=100. Then add the two answers together to get 400.
The answer is B because mean = 4+5+5+5+6 / 5 =5 and the mode equals 5
