Question

The formula P=2(l + w)relates the perimeter P, in decimeters, with the length and width of a rectangle.

Answer 1

Answer:

3. w=P/2-L

Step-by-step explanation:

Given formula:

• P=2(l + w)

Solving for w:

• P=2(l + w)
• P/2 = 2(l + w)/2
• P/2 = l + w
• P/2 - l = l + w - l
• P/2 - l = w
• w = P/2 - l

Correct answer choice is:

• 3. w=P/2-L
