Answer:

Length=18 Width=6

Step-by-step explanation:

Hello, You should first you algebra and and assign the dimensions with letters.

Length=x Width= 1/3x

as its the perimeter you add all the side together

x + x + 1/3x + 1/3x

which equals= 8/3x (this is an improper fraction at the moment)

then we know the total perimeter =48

so 48=8/3 x

so rearrange to get X by it's self

so 48 x 3/8

which x=18
