The formula of the measurement of an exterior angle of a regular polygon is
β = 360°/n
where β = exterior angle and n = number of sides
Therefore,
n = 360°/β = 360°/18° = 20 sides
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
n = 1200
x = 32% of 1200
So, 
We need to find 95% confidence interval.
so, z = 1.96
So, margin of error would be

So, Interval would be

Hence, Option 'c' is correct.
Area = 2831.25 square yards
Perimeter =215.6 yards
EXPLANATION
The area and perimeter of a rectangular field are found using the formula for finding the area and perimeter of a rectangle respectively.
That means, area of the rectangular field is given by the formula,

We just have to substitute

and

into the given formula and evaluate.
This implies that;

This gives the area of the rectangular-shaped field to be;

square yards.
Now for the perimeter, we use the formula

Or

Substituting the values for the length and width gives,



Hence the perimeter of the rectangular shaped field is 215.6 yards.
