The equation is [tex]b=\frac{2A}{h}[/tex]
Step-by-step explanation:
Let us revise how to make a variable subject of an equation
- Write the equation and circle the variable you want to make it subject
- Keep it in one side and move all other in the other side
- Make the coefficient of the subject 1
∵ A = [tex]\frac{1}{2}[/tex] × b × h
∵ b is the subject
∴ Multiply the two sides by 2
∴ 2A = b × h
- Divide both sides by h
∴ [tex]\frac{2A}{h}= b[/tex]
- Switch the two sides
∴ [tex]b=\frac{2A}{h}[/tex]
The equation is [tex]b=\frac{2A}{h}[/tex]
