Question

the area of an equilateral triangle is 2 root 3 cm square what is it semi perimeter

Answer 1

HEYA.....!!!



Your answer ⏬⏬

Area of an equilateral triangle =2√3 cm²

=> √³/4 a² =2/√3

=> a²=2/√3 x 4/√3

=>a²=8/3

=>a= √8/3

and we know that all sides in equaliteral triangle are equal.

Semi perimeter = a+b+c /2

=>√8/3+√8/3+√8/3 /2

=>2.8284/2

=>1.4142 cm

Answer 2

as the area of equilateral triangle = side^2 *(root3/4)

here, 2root3  = side^2 (root3/4)

root3 will cancel,

2=side^2/4

2*4 = side^2

8=side^2

root8 = side

the perimeter of equilateral triangle =3*side 

= 3*root8 

=2*3 root2

=6root2



i hope this will help you
