Answer:
The Area is 10cm, and the perimeter is 14cm
Step-by-step explanation:
Area:
a = w · l 5cm · 2cm =10cm

X varies directly as y would be

x vairies inversly as y would be

not sure if the y is on the bottom or on top from looking at the question
Answer: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
Step-by-step explanation:
One quarter
