The aluminum section's area formula solved for h is 
From the complete question, the expression of the area (A) in terms of variables a, b and h is:
Factor out h from the expression on the right-hand side
Divide both sides of the equation by (a - b)
Remove the bracket
Rewrite the above equation as follows:
Hence, the aluminum section's area formula solved for h is
