Question

the altitude of an equilateral triangle is √3cm . what is perimeter​

Answer 1

Answer:

sorry brooooooooooooooooooooooooooo

Answer 2

Answer:

6cm

Step-by-step explanation:

let side of equilateral triangle be a

altitude divides base side into two equal parts a/2 and a/2

Using pythagorus theorem

a^2=(a/2)^2+(√3)^2

a^2=a^2/4+3

a^2-a^2/4=3

3a^2/4=3

3a^2=12

a^2=12/3

a^2=4

a=√4

a=2cm

perimeter=3a

=3×2

=6cm
