Question

What is length of each side of equilateral triangle having an area of 4underroot3cm²is eqaul to

Answer 1

Answer:

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

given

area = 4√3 cm^2

now,

√3 a^2/4 = 4√3

a^2/4 = 4

a^2 = 4 *4

a = √4*4

a = 4 cm

so, each side of equilateral triangle = 4 cm
