The formula for the perimeter of a rectangle is P=2(l+w)P=2(l+w).
Solve for w.
w=2P−lw=2P−l
w=p2−lw=p2−l
w=p−l2w=p−l2
w=P2+l
D?
P/2 = L+w
w = P/2 - L
nope. And where are your divide symbols?
P/2 = l+w
now go from there.
The correct answer is w = (P - l)/2.
To solve for w in the formula P = 2(l + w), you need to isolate w on one side of the equation.
Step 1: Distribute the 2 to both l and w:
P = 2l + 2w
Step 2: Move 2l to the other side of the equation:
P - 2l = 2w
Step 3: Divide both sides of the equation by 2 to isolate w:
(P - 2l)/2 = w
Simplifying further, you get:
w = (P - l)/2
Therefore, the value of w in the formula for the perimeter of a rectangle is w = (P - l)/2.
To solve for the value of w in the formula for the perimeter of a rectangle, P=2(l+w), we need to isolate w on one side of the equation.
1. Start with the equation: P=2(l+w).
2. Distribute the 2 to both terms inside the parentheses to get: P=2l+2w.
3. Now, subtract 2l from both sides of the equation to isolate the term with w: P-2l=2w.
4. To solve for w, divide both sides by 2: (P-2l)/2=w.
5. Simplify the expression on the right-hand side to get the final solution: w=(P-2l)/2.
Therefore, the solution for w is given by w=(P-2l)/2.
