Answer:
20ft^2
Step-by-step explanation:
The length is currently three feet, if you add two feet to three that makes five feet. Five times four is twenty.
I hope this helps!
Since C is 2mi east of A and 2mi south of B, the shortest distance from A to B would be a straight line which is equal to the hypotenuse of a right triangle with a base of 2mi and a height of 2mi..
d^2=x^2+y^2
d^2=2^2+2^2
d^2=4+4
d^2=2*4
d=√(2*4)
d=2√2 mi (exact)
d≈2.83 mi (to nearest hundredth of a mile)
Submarine: -730
Airplane: 9,144
|-730-9,144|=|-9,874|=9,874
|d|: absolute value
The vertical distance between the submarine and airplane is 9,874 meters.
