Question

If the area of an equilateral triangle is 4√3 cm square, then the perimeter of that equilateral triangle is

Answer 1

12cm

Step-by-step explanation:

√3/4 a² = 4√3

=> a² = 4 × √3 × 4

√3

=> a² = 4 × 4

=> a² = 16

=> a = √16

=> a = 4cm

Perimeter = 4 + 4 + 4 = 12cm

Answer 2

Answer:

Given

area of equi. triangle=4√3 cm square

let side be a

area of equi. triangle=√3/4 side square

according to question

4√3 cm square=√3/4 a square

√3 a square =4*4√3cm square

a square=16√3cm square

a square=16√3/√3cm square

a =√16cm square

a=4cm

hence, side of equilateral triangle=4cm

perimeter of square=3a

=3*4cm

=12cm(and)
