The length of the arrows could represent either the magnitude or the direction of the vectors. If the length represents magnitude, longer arrows would represent larger magnitudes of the vectors. If the length represents direction, the arrows would be all the same length, but pointing in different directions to represent different vectors.
The magnitudes of the vectors. apexs
It depends on the situation. In the UK - an rural roundabout is indicated by a white circle bordered by three arrows facing clockwise - on a blue background.
tell whether the measure could represent the perimeter or the area of a figure
The arrows represent the flow of energy.

The 13 arrows represent the original 13 colonies and the willingness of the country to fight when it is necessary.
Cupid is a Roman god, and his mother is Venus: the arrows represent being "struck" by love.
The 13 arrows on the great seal symbolize the 13 colonies and how they were forged out of war
How energy moves from organism to organism.

This also applies to a food chain - The arrows in a food web represent the flow of energy through the web, further along the arrows/web means that less energy is moving along. The energy flows through arrow to the next consumer, the energy moving through the arrows have less and less energy as the web moves on. To put it in (much) simpler terms, the thing its pointing to eats the other thing.
Forces can be shown in a diagram using arrows. The length and direction of the arrows represent the magnitude and direction of the force, respectively. You can label the arrows with the type of force and its value if known.
Two arrows facing in opposite directions typically symbolize a sense of balance, conflict, or duality. It can represent opposing forces or directions that need to be reconciled or navigated.
