Wittaler [7]
I have included attachment below

so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2

Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,0
Sphinxa [80]

Answer:

Sea\ Level = 0\ ft

The farthest point is the Challenger Deep

Step-by-step explanation:

Given

Highest = +29029ft

Least = -35,797ft

Solving (a): The sea level

Both elevations had signs in front of them.

The sea level is the point at the neutral level, neither positive nor negative.

Hence:

Sea\ Level = 0\ ft

Solving (b): Farthest Point.

The farthest point is the one with the highest magnitude.

Comparing

Highest = +29029ft  to   Least = -35,797ft

-35,797 ft has the highest magnitude.

Hence:

<em>The farthest point is the Challenger Deep</em>
