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 .

I got 9 and 3/8 because you would subtract 18 3/4 from 28 1/8
It is a decimal answer if you used a calculater, and divided then got that answer, then try the same problems just switch the order that you put in the calculater, ex: if you divide 408÷1201 ,and then you get an answer like that, then you would divide it like 1201÷408
I hope this helped :)
C. 16 inches is the correct answer.
