Find the area of the regular hexagon if the apothem is 8 squared root 3 m and a side is 16 m. round to the nearest whole number. 665 m2 1330 m2 998 m2 222 m2

Perimeter = 16 * 6 
Area = (1/2)(perimeter)(apothem)
Area = (1/2) (16 * 6)(8\/3) 
Area = 665.1

The answer is 76° i believe

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
