Choose the correct answer
A
Angles between survey lines
B
Area of irregular plane figures by tracing the boundary
C
Linear distances on a map
D
Height of objects using stadia
Correct Answer
B. Area of irregular plane figures by tracing the boundary
Why is this the answer?
Planimeter (mechanical or digital): measures AREA of an irregular figure on a map or drawing by tracing the perimeter. As the tracing arm is guided around the boundary, the wheel rolls and records area proportional to movement. Used for: plan area from maps, catchment area from topographic maps, cross-section areas for earthwork.
