First, you plot the coordinates to visualize the problem clearly. As you can see in the picture, the longest sides could either be one of those marked in red. This could be initially determined when you use visual estimation. We measure this using the distance formula: d = √[(x2-x1)^2 + (y2-y1)^2)]
Between coordinates (0,3) and (3,6)
d = √[(3-0)^2 + (6-3)^2)]
d= 4.24 units
Between coordinates (2,1) and (5,4)
d = √[(5-2)^2 + (4-1)^2)]
d= 4.24 units
They are of equal length. Both are the longest sides which measures 4.24 units.

Answer:
25%
Step-by-step explanation:
As the given situation the parameters are below:-
Cost of each box = 3 pounds
Amount of cereal in each box = 160 g
now,
160 g of cereal = 100%
and
25% of 1 box of cereal = 25% of 160 g which is
As per the question, it is mention that Jane need her idea to give the equal value of amount as Tim's idea, provided
160 g of cereal costs 3 pounds
and
1 g of cereal will cost
=
40 g of cereal will cost
So, the percentage of the pound is of 3 pounds is 3 ÷ 4 ÷ 3 × 100
= 25%
Therefore as the situation, Jane need to decline the amount by 25% for the same amount as Tim's idea.
