Answer: W = P/2 - L
Explanation:
The equation for the perimeter of a rectangle is expressed as
P = 2(L + W)
where L and W represent the length and width of the rectangle.
P is the perimeter
We want to solve for W. The first step is to divide both sides by 2. We have
P/2 = 2(L + W)/2
P/2 = L + W
Subtracting L from both sides, we have
P/2 - L = L + W - L
P/2 - L = W
W = P/2 - L
