Question 293259: i am just practicing here. This is my question:
The length of a rectangle is 2 ft. more than the width. The perimeter of the rectangle is 20 feet. Find the length. Tell me if this is the correct way.
P= 2L + 2L
P= 2*(2) + 20
P= 4 + 20
P= 24
L= 6 because 24 divided by 4 = 6(answer)

I'm not sure how you got that answer (it's the correct answer) since your steps are incorrect.

Let L = length and W = width


Recall that the perimeter of a rectangle is . Since the length is 2 ft more than the width, we can say that


Start with the given equation.


Plug in and


Distribute.


Combine like terms.


Subtract 4 from both sides.


Combine like terms.


Divide both sides by 4 to isolate W.


Reduce.


So the width is ft and the length is ft
