I'm assuming that you're talking about the dimensions of a rectangle. To find the area, you can multiply the length (2.25 meters) by the width (1.8 meters).
2.25*1.8=4.05
The area would be 4.05 sq. meters
Answer:
The resultant velocity of the airplane is 213.41 m/s.
Step-by-step explanation:
Given that,
Velocity of an airplane in east direction, 
Velocity of wind from the north, 
Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.
We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :


v = 213.41 m/s
So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.
