Answer:
54 cm²
Step-by-step explanation:
Area of a Rectangle Formula: A = lw
We are given 18 as <em>l</em> and 3 as <em>w</em>, so simply plug it into the formula:
A = 18(3)
A = 54
The answer is B. The actual reciprocal is 7/2, since the answer means isn't there its means the reciprocal of the negative or positive sign
Well in order to round 9.42 to the closest whole number we must know that. anything below 5 we round down and 5 and up we round up
So 9.42 becomes 9
of if your wanting to round to the nearest tenth it would be 9.4 you drop the 2 because you rounded down since it was lower than 5.
