simple.
using formula
a square +b square = c square
so
80*80=6400
18*18=324
sum=6400+324=6724
square root=82
a=80
b=18
c=82
so perimeter = 80+18+82 = 180
to find are we will use herons formula
(iam just solving it with out briefing it)
180/2=90
90*(90-80)(90-82)(90-18)root
90*10*8*72root
518400root
720
so area =420unit square
