The formula for the perimeter P of a rectangle is P=2l +2w. What is the result when correctly solving the formula for the variable w?
Subtract 2L from both sides and then divide by both sides by 2.
To solve the formula for the variable w, we need to isolate it on one side of the equation. Let's begin by rewriting the formula:
P = 2l + 2w
To isolate w, we need to get rid of the 2l term on the right side. We can do this by subtracting 2l from both sides of the equation:
P - 2l = 2w
Next, we can simplify the equation further:
2w = P - 2l
To find the value of w, we divide both sides of the equation by 2:
w = (P - 2l) / 2
So, when correctly solving the formula for the variable w, the result is w = (P - 2l) / 2.
