Question

A=(a+b)2h Solve for a. a=2Ah−b a=2A−bh a=2Ah+b a=Ah2−b

Answer 1

A= 2bh/1-2h idk of I’m right or not

Answer 2

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

Step-by-step explanation:

Given : Expression
`A=(a+b)/(2)* h`

To find : Solve for a ?

Solution :

Step 1 - Write the expression,

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

Step 2 - Multiply by 2 both side,

`2A=a+b* h`

Step 3 - Divide by h both side,

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

Step 4 - Subtract by b both side,

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

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

So, Option a is correct.
