The statement best describes deena's error is: Find acceleration by finding the area of the rectangle above the line.
Acceleration is given by the ratio of Resultant or total force acting on any object and the its mass.
Deena made a chart to summarize features of a velocity vs. time graph for objects with constant acceleration and objects with constant velocity.
In the velocity time graph, the area under the curve shows the displacement of the object and the slope represents the acceleration.
Thus, the deena's error is Find acceleration by finding the area of the rectangle above the line.
