Answer:  " b = 3 ⅕ ; or, write as: 3.2  .
_____________________________________
Given:  "A = (1/2) * b * h " ;

 ↔  A = (b * h) / 2 

2A = (b*h) ;

2A/ h = b ;

↔ b = (2A) / h ;

Given A = 48 ;  and h = 30 ; Plug in these values; and solve for "b" ; 

→ b = (2*48) / 30 ; 

        = 96/30 ; 

        = (96÷6) / (30÷6) ;

→ b = 16/5 ;  = 3 <span>⅕ ; or, write as: 3.2 .
