Step-by-step explanation:
The given function is
Where
Notice half the period is
Now, in the first function
Notice that this function is in the form:
Where , which definition is

Which means the first function is has half the period of the given function.
322.24 meters
The scale is 4 meter per centimeter. Multiply 5.3 by 4 to get 21.2 meters. Multiply 5.3 by 4 to get 15.2 meters. Multiply 21.2 by 15.2 to get 322.24
300
find the sum of area of all sides
135°
formula = (n-2) * 180, whereby 'n' is the number of sides.
therefore, (8-2) * 180 = 1080°
1080° ÷ number of sides
= 1080° ÷ 8
= 135°
