Answer:

b = [tex]\frac{2a}{h}[/tex]

Step-by-step explanation:

Given

a = [tex]\frac{1}{2}[/tex] bh

Multiply both sides by 2 to clear the fraction

2a = bh ( divide both sides by h )

[tex]\frac{2a}{h}[/tex] = b

Answer: b=2a/h

Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
