Question

7.
If the area of an equilateral triangle is 4√3
cm? then its perimeter is

​

Answer 1

Answer:

Given

area of equi. triangle=473 cm square

let side be a

area of equi. triangle=V3/4 side square

according to question

4V3 cm square=V3/4 a square

V3 a square =4*4v3cm square

a square=16V3cm square

a square=16V3/V3cm square

a =v16cm square

a=4cm

hence, side of equilateral triangle=4cm

perimeter of square=3a

=3*4cm

=12 cm(and)

Answer 2

Answer:

12cm

Step-by-step explanation:

area=√3 *a^2/4

a^2=16

a=4

perimeter=3*a=3*4=12cm
