Can the sides of a quadrangle be 4.8 m, 2.6 m, 9 m, and 1.5 m?

By the property of an arbitrary quadrilateral, the length of any of its sides cannot exceed the sum of the lengths of its three other sides.

In this case, we observe the following: 4.8 + 2.6 + 1.5 = 8.9 m.Thus, the sum of the three sides (8.9 m) is less than the fourth side (9 m), which means that such a quadrangle does not exist …
