The area of an equilateral triangle with side 4 cm.

4 ≈ 6.93 cm²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = ← s is the side length

here s = 4, thus

A =

   =

   = 4 ≈ 6.93 cm²

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
