The formula for area is as follows:
area = length x width
Substitute the known values into the formula:
240 = (length) x 8
Divide 8 from both sides to get the following equation:
(240 / 8) = length
Simplify the left side of the equation:
30 = length
Therefore, Emily will need to use 30 tiles in each row. The answer is C) 30 tiles.
I hope this helps!
