Question

Solve the formula for calculating the perimeter of a parallelogram with sides b and c for c

Answer 1

Answer: OPTION B.

Step-by-step explanation:

To solve for c from the equation shown in the image attached, you must apply the proccedure shown below:

- Subtract 2b from both sides of the equation:

$P-2b=2b+2c-2b\\P-2b=2c$

- Now, you must divide by 2 to both sides of the equation as following:

$\frac{P-2b}{2}=\frac{2c}{2}\\c=\frac{P}{2}-b$

Then the answer is the option B.
