Hello Mitchell.
Let's set this up.
We have a rectangular table top so we need to know the length(L) and width(W)
The first sentence tells us L = 3W
The 2nd sentences tells us W = 1 1/3 meters = 4/3 meters
Based on this, we can determine the length.
L = 3W = 3 (4/3) = 4 meters
Now Area, A=LW
A = (4)(4/3) = 16/3 meters = 5 1/3 meters
