the perimeter is 48, the length is 2 times the with. what is the width and length. I got the answer but how do you figure it out, is it a formula?

• math -

What shape are you dealing with?
A rectangle?

If so, then perimeter = 2L + 2w

let the width be W
"the length is 2 times the with" ---> l = 2w

so 2L + 2(2w) = 48
6w = 48
w = 8
then l= 16

• math -

P = 4W + 2W
48 = 6W
8 = W
