BAF and FAD is the answer
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.
Let's solve ~
I hope you understood the procedure, please let me know if you have any doubts
X = 12y - 20
y = 12y
Y is obviously greater than 20 when you multiply it by 12, so that's a hint.
x = 42
y = 22
3.5 • 12 + 22 = 64
I hope this helped you!
