area of an equilateral triangle=√3/4xa^2
given area =4√3
so, √3/4a^2=4√3
a^2=4√3 x 4 /√3
a= √4x4
a= 4 units
s= a+b+c/2
a=b=c=4
s= a+a+a/2
s= 4+4+4/2
s= 12/2= 6 units
the semiperimeter is 6 units
given area =4√3
so, √3/4a^2=4√3
a^2=4√3 x 4 /√3
a= √4x4
a= 4 units
s= a+b+c/2
a=b=c=4
s= a+a+a/2
s= 4+4+4/2
s= 12/2= 6 units
the semiperimeter is 6 units
