500ft, 600ft and 700ft
Explanation:
If
All three sides add to make 1800 so we can write

Explanation:
#"let the shortest side "=x#
#"then the other 2 sides are "x+100" and "x+200#
#rArr"perimeter "=x+x+100+x+200=3x+300#
#"we are given perimeter "=1800#
#rArr3x+300=1800#
#"subtract 300 from both sides"#
#rArr3x=1500rArrx=1500/3=500#
#"sides are "x=500,x+100=600" and "x+200=700#
