An equilateral triangle has area of 36 square root 3 square units. What is the side length?

The side length is 3.72 units

Step-by-step explanation:

Area A = √(36)units

area of an equilateral triangles is

A = [√(3)/4] * s²

A = area

s = side length

√(36) = [√(3)/4] * s²

Take the square of both sides

[√(36)]² = [(√(3)/4) *s²]²

36 = (3/16) * s⁴

36 * 16 = 3s⁴

576 = 3s⁴

S⁴ = 576 / 3

S⁴ = 192

Take the fourth root of both sides

4√(s⁴) = 4√(192)

S = 3.72 units

The side length of the equilaterial triangle is 3.72 units

d. 9

step-by-step explanation:

54/12 = 4.5

sf = 4.5

so x = 2 · 4.5 = 9
