Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
The answer is the last option because the graph goes no greater than 75 and it also goes no greater than zero but it does hit zero and 75
The length of the rug would be 18m
LxW=A
14x18=252
R= d/t
you just divide both sides by t to isolate r
