Answer 2

Option D:
`(2A)/(h)-B` is the value of b

Step-by-step explanation:

Given that the formula for the area of a trapezoid is
`A=(1)/(2)h(B+b)`

We need to solve the formula for b.

The value of b:

Let us solve the formula
`A=(1)/(2)h(B+b)` to determine the value of b.

Multiplying both sides of the formula by 2, we get;

`2A=h(B+b)`

Dividing both sides by h, we get;

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

Subtracting both sides of the formula by B, we have;

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

Thus, the value of b is
`(2A)/(h)-B`

Hence, Option D is the correct answer.
