Write an equation from the information given: a rectangle is twice as long as it is wide. the perimeter of the rectangle is 18. im very confused can someone out?

okay! the perimeter is the total we're going to be constructing an equation for, so it'll be on the right side of the equals sign.

? + ? = 18

now, we know that it's twice (or 2x) as long as it is wide. this can be represented by 2l, or 2x. the variable doesn't matter.

2l + ? = 18

what about the other unknown? well, the width is unaffected in this equation. so all you have to do is substitute it in!

2l + w = 18

this is the equation we come up with given the limited information.

if this helped, make sure to thank me and rate me, and maybe give me brainliest if i /really/ helped! good luck!
