Question

Tracy needs to find the length and width of the equipment storage room where she works. The room is 2 meters longer than it is wide. Its perimeter is 24 meters. Fine the width in meters.

Answer 1

Call length, l and width,w. We have
l=w+2. since the length is 2 meters longer the width. The perimeter is:
2l+2w=24, substituting l=w+2:
2(w+2)+2w=24
solve for w. Once you have w, go back to l=w+2 to get the length, l.

Answer 2

You lost me... what do I do to figure out the answer?

Answer 3

solve:
2(w+2)+2w=24

Answer 4

but i dont know what w is

Answer 5

you need to be able to solve basic algebraic equations to get the answer. You have to find w, using algebra...

Answer 6

I'll give you the first step:
2w+4+2w=24
go from there...

Answer 7

idk how to do that

Answer 8

I'd review your basic algebra...
basically, collect "like" terms (example 3x+10x can be simplified to 13x).
isolate unknown variable (example 5x+20=80, becomes 5x=60...then we get x=12). good luck :)

Answer 9

its 5

Answer 10

yep. so now we have w=5. and we know that l=w+2. Input w=5 to get the length, l

Answer 11

actually you don't even need to since the question only asked for the width. so you're done

Answer 12

ik.
