Answer:
Horizontal displacement = 100 km
Position with respect to sea level = -0.4km
Step-by-step explanation:
Let the displacement downwards be negative displacement and displacement upwards be positive.
The horizontal distance from the shore remains constant whereas the displacement from the sea level varies as the submarine moves.
The upward displacement = 3/5 km
Downward displacement = - 1/10 km and - 9/10 km
Total displacement = 3/5km - 1/10 km - 9/10km = - 2/5 km = - 0.4 km
Horizontal distance from the shore = 100km

=================================================
Work Shown:
s = side length of equilateral triangle = 1 cm
A = area of equilateral triangle with side length 's'



This is just one of the 6 equilateral triangles (see diagram below)
Multiply by 6 to get the area of all 6 equilateral triangles, or the entire hexagonal area
