Answer 2

Answer:

Step-by-step explanation:

perimeter of triangle = 16+16+16=48

semi-perimeter=48/2=24

area of triangle = root of 24*24-16*24-16*24-16

                           = root of 24*8*8*8

                           = 8 root of 24*8 ( take one 8 )

                            = 8 root of 8*3*8

                             = 8*8 root of 3

                               64 root 3
