Question

Did i get this right????

Answer 1

Answer and Step-by-step explanation:

We are given the perimeter equation: P = 2w + 2l, where w is width and l is length.

We want to find l. We do this by getting all of the variables to one side of the equation and have l by itself on the other side of the equation.

We start off by subtracting 2w from both sides of the equation.

P - 2w = 2w + 2l - 2w

P - 2w = 2l

Now we divide both sides of the equation by 2.

`(P-2w)/(2) = (2l)/(2)`

`(P-2w)/(2) = l`

To simplify it further, we can write the equation as such:

`l = (1)/(2)P - w`

Have a good day!
