Answer 1

a = 2A/h - b

Explanation:

For this question the answer is a = 2A/h - b

We have to isolate the variable by dividing each side by factors that don't contain the variable.

We'll have our final answer as : a = 2A/h - b

Answer 2

Answer:
`a=(2A)/(h)-b`

Explanation:

The given formula :
`A=(a+b)/(2)\cdot h`

Then , to solve the formula for a , first divide both sides by h and multiply both sides by 2 , we get

`(2A)/(h)=a+b`

Now, subtract b on both the sides , we get

`(2A)/(h)-b=a`

Or we can write it as
`a=(2A)/(h)-b`

Hence, the formula for a is given by :-
`a=(2A)/(h)-b`
