whose height is 3 cm.
B​

Answer 1

Answer:

Length =3cm

perimeter = 9 cm

Step-by-step explanation:

In equilateral triangle all sides are equal .

And the formula of perimeter in equilateral triangle is 3×side

Answer 2

Answer:

2√3

Step-by-step explanation:

let side of equilateral triangle be a

area of triangle = 1/2×b × h

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

1/2 × a × 3 = √3/4 a^2

3/2a = √3/4a^2

a^2/a = 3/2/√3/4

a = 3×4/2×√3

a = 2√3

perimeter of equilateral triangle = 3a

= 3 × 2√3

= 6√3
