∻Solution by Steps∻ ‖ step 1 ⋮ The area of rhombus ABCD is given as 6. The area of triangle ADP can be expressed as $ y = \frac{1}{2} \times base \times height $. ‖ ‖ step 2 ⋮ As point P moves along the path from A to B to C to D, the length of the path can be denoted as $ x $. The relationship between $ y $ and $ x $ will depend on how the height of triangle ADP changes as P moves. ‖ ‖ step 3 ⋮ Graph A and B show a similar trend where the area increases and then decreases, which is consistent with the behavior of triangle ADP as P moves. Graph C shows a constant area, which is not applicable here. Graph D shows an increase and then a decrease, which aligns with the expected behavior. ‖ ‖ step 4 ⋮ Therefore, the graph that best represents the relationship between $ y $ and $ x $ is Graph D, as it reflects the increase in area up to a point and then a decrease as P moves towards D. ‖ ***D*** ∻Key Concept∻ ⚹Area of triangles and rhombuses⚹ ∻Explanation∻ ⚹The area of a triangle changes based on the position of its vertices, and in this case, as point P moves, the area of triangle ADP varies accordingly. The graph that reflects this relationship shows an increase followed by a decrease.⚹◊What is the relationship between the distance traveled along the path and the area of triangle $ \triangle ADP $ as point $ P $ moves through the vertices of rhombus $ ABCD $?⍭ Generate me a similar question◊
