Question

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

Answer 1

Answer: OPTION B.

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:

`(P-2b)/(2)=(2c)/(2)\\c=(P)/(2)-b`

Then the answer is the option B.
