hey..
let the side of triangle be x
x + x + x = 48
3x = 48
x = 48/3
x = 16
therefore the side of the triangle is 16cm

Answer:
Step-by-step explanation:
perimeter = 48cm --->
side = 48/3 = 16cm
height = sqrt( 16^2 - 8^2)
= sqrt( 256 - 64)
= sqrt( 192)
= 8*sqrt(3)
area = height * base / 2
= 16*8*sqrt(3)/2
= 64*sqrt(3).
