↓Steps Explained:↓



Given an equilateral triangle with side (a) equal to 6

Calculate the other relevant items in this triangle

Calculate Perimeter:

P = 3a

P = 3 x 6

P = 18

Calculate Semiperimeter s:

s  =  P
  2

s  =  18
  2

s = 9

Calculate Area (A):

A  =  a2√3
  4

A  =  62√3
  4

A  =  36√3
  4

A  =  62.35382907248
