Answer: b = " [tex] \frac{2A}{h} [/tex] " .
_______________________________________________________
Explanation:
_______________________________________________________
A = (1/2) * b * h = (b * h) / 2 ;

→ A = (b * h) / 2 ;

Rearrange the formula / equation ; and solve in terms of "b" ;

Multiply each side of the equation by "2" ;

2 * A = 2* { (b * h) / 2 } ;

to get:

2 A = (b * h) ;

↔ (b * h) = 2 A ;

Divide each side of the equation by "h" ;
to isolate "b" on one side of the equation; & to solve "in terms of, "b" " ;

→ (b * h) / h = (2 A) / h ;

to get:
_______________________________________________________

→ b = " [tex] \frac{2A}{h} [/tex] " .
