3 Make one diagonal line with 5 cm, 1 cm, and 4 A rectangle with fixed diagonal lines has the
3 cm sticks and one diagonal line with 4 cm and greatest area when the diagonal lines are
perpendicular and the difference between the
6 cm sticks. Or make one diagonal line with 6 cm, lengths of the diagonal lines is the smallest.
Therefore, Mike and John have bigger areas
1 cm, and 3 cm sticks and one diagonal line with between the lengths of land than Kevin because
the difference of the diagonals is 16 14 2 m,
4 cm and 5 cm sticks. The difference between the which is less than 20 10 10 m. Between Mike
and John, the diagonals of Mike’s land are
lengths of the diagonals for both possibilities will perpendicular, so Mike has the biggest piece of
land.
be 1 cm, which is the smallest difference.
Therefore, the quadrilateral with the greatest area
1
is 10 9 2 45 cm2.
