Answer :
perimeter=2legnth+2width
width:legnth=3:5
perimiter=2(legnth+width)
144=2(legnth+width)
divide both sides by 2
72=legnth plus width
3+5=8
72/8=9
3 times 9=width=27
5 times 9=legnth=45
width=27 ft
legnth=45 ft
width:legnth=3:5
perimiter=2(legnth+width)
144=2(legnth+width)
divide both sides by 2
72=legnth plus width
3+5=8
72/8=9
3 times 9=width=27
5 times 9=legnth=45
width=27 ft
legnth=45 ft
