Answer:
feet : Shark is 72 feet below sea level.
Step-by-step explanation:
Let x represent depth of the shark.
We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be 
.
We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be 
.We can represent this information in an equation as:
To find shark's position, we need to solve for x.
Therefore, feet represents shark's elevation, which represents that shark is 72 feet below sea level.

Answer:
45 square centimeters
Step-by-step explanation:
The area of the triangle is given by ...
A = (1/2)bh
where b is the base, 2 cm + 3 cm = 5 cm, and h is the height, 6 cm.
A = (1/2)(5 cm)(6 cm) = 15 cm^2
__
The area of the rectangle is given by ...
A = bh
where b is the base, 12 cm, and h is the height, 2.5 cm.
A = (12 cm)(2.5 cm) = 30 cm^2
__
The area of the whole figure is the area of the triangle added to the area of the rectangle:
drawing area = 15 cm^2 + 30 cm^2 = 45 cm^2
