Answer:
[tex]b\leq 12[/tex]
Step-by-step explanation:
Formula of a rectangle:
[tex]a=h*w[/tex]
a = area
h = height
w = width (or base length)
Replace the variables with the numbers given:
[tex]48=4*b[/tex]
Divide both sides by 4:
b = 12
Since 48 is the max, the number can only be equal to or lower than 12:
[tex]b\leq 12[/tex]
