If you think about it, an octagon is made up of 8 triangles. So you first find the area of one triangle then multiply it by 8 for the total area:
A=1/2bh
A=1/2(9.9)(12)
A=59.4

59.4 x 8= 475.2

Therefore the total area for the octagon should be 475.2 units^2

Hope this helps !

The following table shows the number of hours some students of a of a class listen to music each day.
seraphim [82]

Answer:

Histogram B best represents the data.

Step-by-step explanation:

student:     Hours:

a                0.6

b                0.5

c                2.5

d               2.5

e               1.5

f                2.5

g               0.5

h               1.5

 I               1.5

 j               2.5

 k              2.5

 l               2.5

m              1.5

n               1.5

o               1.5

Since clearly from the table we could see that none of the student spend  more than 3 hours in listening music each day.

Hence, the graph in option A and option D are incorrect.

Now we arrange our data in the interval of 1 unit to get:

Interval                   Number of students

0-1                                       3

1-2                                       6

2-3                                      6

Hence, the histogram that represents this data is:

Histogram B
