Topic Two Now we can figure out how much it’s going to cost us to put a new rug in our house. We just have to figure out the square footage, and how much a square foot.

5/1/2020  The area of a square or a rectangle is found by multiplying the length by the height.



5 Area =lxh 5 3 Area = l x h 12
