How to solve for b2 in the equation A = 1/2 * h * (b1 + b2) with given values

To solve for b2 in the equation A = 1/2 * h * (b1 + b2), we need to substitute the known values and rearrange the equation accordingly.

We are given:

• A = 16
• h = 4
• b1 = 3

Now, let’s substitute these values into the equation:

16 = 1/2 * 4 * (3 + b2)

This simplifies to:

16 = 2 * (3 + b2)

Next, divide both sides by 2 to isolate the term with b2:

8 = 3 + b2

Now, subtract 3 from both sides:

8 - 3 = b2

This gives us:

b2 = 5

So the value of b2 is 5.
