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. What does x represent in the equation

30 square feet

Step-by-step explanation:

Number of tiles used for covering the kitchen floor = 10

Area covered by the floor = 6 * 5 feet^2                                                

                                        = 30 square feet

Length of each tiles = 3 feet

Width of each tiles = w feet

Area covered by each tiles = 3w square feet

Then the equation can be written as

3w * 10 = 30

30w = 30

w= 30/30      

   = 1 feet

10 *3w = 30

the answer to the expression is 83

answer is x<
