1. A regular hexagon with side 12.
To find the height or the apothem..my equation:
h²+ 6² = 12²
h²+ 36 = 144
h²= 108
h= 6√3
Then to find the area of the regular hexagon...by formula of A=1/2ap,my equation is...
A= (1/2)(6√3)(72)
I got the equation up to here, but i have no idea of how to multiply the radical.....help with this please...(multiplying the radical...)

.
Then please answer this question...
