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

Answer:

Option a - $a=\frac{2A}{h}-b$

Step-by-step explanation:

Given : Expression $A=\frac{a+b}{2}\times h$

To find : Solve for a ?

Solution :

Step 1 - Write the expression,

$A=\frac{a+b}{2}\times h$

Step 2 - Multiply by 2 both side,

$2A=a+b\times h$

Step 3 - Divide by h both side,

$\frac{2A}{h}=a+b$

Step 4 - Subtract by b both side,

$\frac{2A}{h}-b=a$

Therefore, $a=\frac{2A}{h}-b$

So, Option a is correct.
