Answer:
350 ft
Step-by-step explanation:
you have to find the exact perimeter by sbutracting the total length from the length of the field by doing[tex]115-100=15[/tex] which gives you how wide the bleachers are. you then have to make a formula which i set as [tex]P=3s+2s+2s+s[/tex]. i filled it in as [tex]P= 3(20)+2(100)+2(15)+60[/tex]. It simplifies to [tex]P=60+200+30+60=120+230=350ft[/tex]
