The sum of the exterior of an n-sided convex polygon is half the sum of…

Correct Answer: Option A

Explanation

sum of exterior angles = 360^o
Sum of interior angle = (n – 2) x 180
360 = (frac{1}{2}) x(n – 2) x 180(90^o)
360 = (frac{1}{2}) x(n – 2) x 90^o
(frac{360}{90}) = a – 2
4 = n – 2
n = 4 + 2 = 6
