PLEASE ANYONE HELP MEEE!!!!

An equilateral triangle has an apothem of 5 cm. Find the perimeter of the triangle to the nearest centimeter.

A.

26 cm
B.

52 cm
C.

75 cm
D.

100 cm"

Answer 1

Well, as the  apothem is  = s/2*Tan(180/n). 
5 = S/2*Tan(180/3), S = 17.32 cm. 
P = 17.32 + 17.32 + 17.32 = 52 cm.
So your option will be the second one: B. 52 cm.
Hope this is useful
