Not sure how to ask my question?

Need help on writing a formula for trapezoid A=h(B=+b)
____
2
without parentheses and multiplication. Hope this makes sense. If it could be explained that would be great.

Not sure if I understood the question.

Does it mean that we need to write the formula
A=(B+b)h/2
without using parentheses AND without using the multiplication sign?
Would it be:
A=Bh/2 + bh/2
