Answer:
For area, square unit is used as the area is calculated using two dimensions length and breadth.
For volume, cubic unit is used as the volume is calculated using three dimensions length, breadth and height.
Step-by-step explanation:
Area refers to the space occupied by a two dimensional flat object in a plane. For area, square unit is used as the area is calculated using two dimensions length and breadth.
Volume is defined as the space occupied by the three-dimensional object. For volume, cubic unit is used as the volume is calculated using three dimensions length, breadth and height.

Answer:
- Maria–Ava: 15.7 feet
- Lucas–Maria: 10.1 feet
- angle at Maria: 50°
Step-by-step explanation:
The cosine and tangent functions are useful here. The relevant relations are ...
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
__
The distance from Maria to Ava (ma) is the hypotenuse of the triangle, so we have ...
cos(40°) = 12/ma
ma = 12/cos(40°) ≈ 12/0.76604 ≈ 15.7 . . . feet
__
The distance from Lucas to Maria (ml) is the side opposite the given angle, so we have ...
tan(40°) = ml/12
ml = 12·tan(40°) ≈ 12·0.83910 ≈ 10.1 . . . feet
__
The angle formed at Maria's position is the complement of the other acute angle in the right triangle:
M = 90° -40° = 50°
In summary, ...
- Maria–Ava: 15.7 feet
- Lucas–Maria: 10.1 feet
- angle at Maria: 50°
