The formula P=2(l + w)relates the perimeter P, in decimeters, with the length and width of a rectangle.
Degger [83]

Answer:

3. w=P/2-L

Step-by-step explanation:

<u>Given formula:</u>

  • P=2(l + w)

<u>Solving for w:</u>

  • 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

<u>Correct answer choice is:</u>

  • 3. w=P/2-L

600 feet of fence surround a rectangular playground that is 100 feet wide. How long is the playground? A.400 b.500 c.300 d.200
Paladinen [302]

Answer:

A.400

Step-by-step explanation:

Well perimeter for a rectangle is l+l+w+w

100+100+l+l=600

200+2l=600

<em>Subtract 200 from both sides</em>

2l=400

<em>Divide both sides by 2</em>

l = 400 feet

The length of the rectangle is 400 feet long.
