What is the step by step method for solving A=1\2bh(a+b)

To solve for A in the equation A = 1/2bh(a+b), follow these steps:

1. Simplify the equation by multiplying 1/2 by both bh and (a+b). This will give you: A = 1/2 * b * h * (a+b).
2. Distribute the 1/2 to the terms within the parentheses. This will give you: A = (1/2)*(ba + bb)*h.
3. Further simplify by multiplying (ba + bb) by h. This will give you: A = (1/2) * (ba + bb) * h.
4. Simplify the expression within the parentheses by combining like terms. This will give you: A = (1/2) * (b^2 + ab) * h.
5. Multiply (b^2 + ab) by h. This will give you the final expression: A = (1/2) * (b^2h + abh).

Therefore, the solution is A = (1/2) * (b^2h + abh).
