Answer:
She need 10.5 inches border
Step-by-step explanation:
Length of box =[tex]\frac{1}{2} inches[/tex]
Breadth of box =[tex]4\frac{3}{4} inches[/tex]
Breadth of box =[tex]\frac{19}{4} inches[/tex]
Height of box = 7 inches
Now we are given that Soledad wants to run a border around the top of the box.
So, Length of top = Perimeter = [tex]2(l+b)=2(\frac{1}{2}+\frac{19}{4})=10.5[/tex]
Hence She need 10.5 inches border
