Okay first thing, we want to know how big the square tabletop is which is 1.69cm^2. We also need to know the formula to finding the area of a square which is A=S^2. Now we square root 1.69m^2 because we want to find one side of the square.
√1.69m^2 = 1.3m
If we use the formula A of square= S^2 we will probably get 1.69m^2, lets try it!
1.3x1.3 = 1.69m^2
Don't forget the SS or simple sentence!
Kai will need 1.3m of laminate.
~Also remember to study for the test! (I am so scared >.<)~
