Answer:
6 feet.
Step-by-step explanation:
Peter measured the width of one cardboard strip as = [tex]2\frac{3}{4}[/tex] feet.
He measured the width of second cardboard strip as = [tex]3\frac{2}{3}[/tex] feet.
The combined width of the cardboard strip = [tex]2\frac{3}{4}[/tex] + [tex]2\frac{3}{4}[/tex]
= [tex]\frac{11}{4}[/tex] + [tex]\frac{11}{3}[/tex]
= [tex]\frac{33+44}{12}[/tex]
= [tex]\frac{77}{12}[/tex]
= [tex]6\frac{5}{12}[/tex] ≈ 6 feet
The combined width of the cardboard is about 6 feet.
