which one are you in the pic
the girl. lol
perimeter is length+length+width+width
the length is 6, twice the width.
so 6=2 X ?
Not the answer you are looking for? Search for more explanations.
hmm so 2L X 2W=102?
Perimiter= 2(width) + 2(length)
The length is 6 meters more than twice the width
Now put this value in for L
2(2W+6) + 2W= 102
Now we know the width...
Length= 2W+6 (from before)
perimeter= 2L + 2W
so substitute our length formula in for L
and 102 in for perimeter
102=2(6+2W) + 2W
which would give you?
i dont know why im still confused
so 2 x length and 2 x width =102.
and then u add 6 to width?
Yes, we want to get the equation into a form that only has one variable.
In this case, they give us the hint.
When they say "The length is 6 meters longer than twice the width"
We can write like this..
Length=6 meters longer then twice the width
Now we have the length in terms of the width
and we can rewrite the equation all in terms of the width and therefore solve for it.
Once we know the width, we use the same piece of info to figure out the length (just plug the value of W and solve for L)
Hope that helps!!!
