I will have to try to explain in words since I don't have a square root icon
FORMULA USED is A=1/2 a X P
substitute the given info
150 sq. rt 3= 1/2 X 5 sq, rrt, 3 X P
multiply all terms by 2 to eliminate the fraction
300 sq, rt 3= 5 sq, rt 3 X P
DIVIDE by sq rt of three
300= 5P
60= Perimeter since the figure is a hexagon ( 6 sides)
divide the perimeter by 6
the side 10
I hope can understand the solution
I do not know what to answer here can you repost this question and make it a little bit more clear as i am sure it is really confusing to everybody else as it stands right now<span />
