On the grid, graph the relationship between cost and weight of strawberries for each supermarket. Use 2 units on the horizontal axis to represent 1 pound for the x interval from 0 to 3. Use 1 unit on the vertical axis to represent $0.50 for the y interval from 0 to 6. B. Find the slope of each line. Then tell what the slopes represent and how they help you determine which supermarket has less expensive strawberries. C. Which supermarket has less expensive strawberries per pound? Explain how you determined your answer.

Let x be the width of the playground, then 3x is the length of the 
playground

х * 3х = 75
3x² = 75
x² = 25
x = 5 m (width)
5*3=15 m (length)

Perimeter = 2(5+15) = 2*20 = 40 meters.
