Step-by-step explanation:
1st History test: 73
2nd History test: 77
3rd History test: 81

5th History test: 89
73+77+81+85+89 = 405
405/5 = 81
Looking at the attachment, we'll determine entire hexagon area with this formula:
area = apothem^2 *Number of sides * tan(180/n)
area = 17.32^2 * 6 * tan (30)
area =
<span>
<span>
<span>
299.9824
</span>
</span>
</span>
* 6 * 0.57735
area = <span><span><span>
1,039.16903184
</span>
</span>
</span>
Now we subtract the triangle area (16*20 = 320)
shaded area = <span>
1,039.16903184
-320 = </span>
<span>
<span>
<span>
719.16903184
</span>
</span>
</span>
<span>answer is D
