Question

area of an equilateral triangle is 36 square root 3 cm square find the length of its sides and its perimeter​

Answer 1

Answer:

area = √3/4 a² where a is side

√3/4 a² = 36√3

a²/4=36

a² = 36*4

a = 6*2

=12

perimeter =4a

= 4*12

=48cms

Answer 2

Area of equilateral triangle of side a = a²√3/4

a²√3/4 = 36√3

a² = 36*4

a = 12

perimeter of equilateral triangle = 3a = 3*12 = 36 cm.
