Answer:
Correct option: first one
"StartFraction P minus 2 l Over 2 EndFraction = w"
Explanation:
First we start from the perimeter equation:
P = 2*l + 2*w
Then, we need to solve for w, so we need to isolate it.
The first step is subtracting 2*l from both sides of the equation:
P - 2*l = 2*w
Then, we divide both sides by 2:
w = (P - 2l) / 2
So the correct option is the first one:
"StartFraction P minus 2 l Over 2 EndFraction = w"
