- Area of rectangle = length × breadth .
<u>procedure</u><u> </u><u>:</u>
putting value of the given data into formula :
Area of rectangle = 12km ×2 km
= 24km ^2
Ans = 24km^2

Answer:
Step-by-step explanation:
It’s 168 because it’s area and area means multiplication, so you would do 14 x 12 = 168
Answer:
The formula for period is T = 1 / f , where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.
To get period from frequency, first convert frequency from Hertz to 1/s.
Now divide 1 by the frequency. The result will be time (period) expressed in seconds.
-1 (-12 - 9i) + 4i (-12 - 9i)
= 12 + 9i + -48i + 9i^2
= 9i^2 + 39i + 12
