Question

Find the length of each side of an equilateral triangle having an area 9 root 3 cm square

​

Answer 1

Step-by-step explanation:

Area of an equilateral triangle = √3/4 a^2

where a is the side of the triangle

√3/4 a^2 = 9√3 cm^2

a^2 = 9√3 cm^2 × 4/√3

a^2 = 9 × 4 cm^2

a^2 = 36 cm^2

a = √(36 cm^2)

a = 6 cm
