The area of a regular hexagon is 150√3 square cm. if the apothem is 5√3 cm, what is the length of each side?

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

B is the answer
Her estimate is wrong. She got her estimation from b
