### Kevin M's Textbook Question 2.4

#15. Kai needs to replace the strip of laminate that is glued to the vertical faces on a square tabletop. The table top has an area of 1.69m^2. What length of laminate does she need?

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

√1.69m^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 >.<)~
