write an equation using the variable X to model this situation.

Question

Mary put new tiles on her kitchen floor.  The floor measures 6 feet long by 5 feet wide. She used 10 tiles to cover the entire floor. Each tile was 3 feet long. Write an equation using the variable X to model this situation. 

Answer 1

Area = 6(5) = 30 ft^2 = 10(3x) = 30x where x= the tile's width

each tile is 3 feet by 1 foot = area of 3 ft^2. 10 tiles = 3(10) = 30 ft^2
