Paaralellogram has 2 pairs of paralell sidess therefor there are 2 pairs of sides with same legnth perimiter=legnth+widht+legnth+width since the opposite sides ar the same sinnce paralell perimiter=2legnth +2width
perimiter=15.42 legnth=2.93 subsitute 15.42=2(2.93)+2width 15.42=5.86+2width subtract 5.86 from both sides 9.56=2width divide both sides by 2 4.78
