Beni uses two same-size poster boards for a science project. She uses 2\3 of the red poster board for the project. She uses more of the blue poster board than the red. Which fraction could be the part of the blue poster board Beni uses for the science project?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
