What is the median of 1, 3, 6, 8, 9, 9
Answer choices: A. 6
B. 7
C. 8
D. 9

B

Step-by-step explanation:

The median is the middle value of the data arranged in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.

1,  3,  6,  8,  9,  9

           ↑ middle

median = = = 7 → B

 300 ft.²   .

Explanation:

We need to find the area of the rectangle:

Area:  A = L * w = length * width = 12 ft. * 18 ft. = 216 ft.²

Then we need to find the area of the TRAPEZOID that is on top of the rectangle:

Area:  A = (1/2) * (base 1 + base 2) * height 
 
             = (1/2) * (18 ft. + 10 ft.) * 6 ft.
   
             = (1/2) * ( 28 ft.) * (6ft.)
      
             =   84 ft.²

Now, we add the 2 (TWO) areas together, to get the

   216 ft.²  +  84 ft.²  = 300 ft.²  .
