x < -2 OR x > 7
Answer:
432 tiles
Step-by-step explanation:
First, convert the dimensions of the table to inches.
There are 12 inches in a foot, so multiply 1.5 and 2 by 12.
1.5(12) = 18
2(12) = 24
So, the dimensions of the table in inches are 18 by 24.
Find the area of the table using the formula, A = lw
A = lw
A = (18)(24)
A = 432
So, the area is 432 square inches.
Since each tile is one square inch, the table will fit 432 of these.
So, Ravi will need 432 tiles.
