उत्तर
No, it is not possible to construct a triangle with lengths of its sides as 4 cm, 3 cm and 7 cm because here we see that sum of the lengths of two sides is equal to third side i.e., 4 + 3 = 7.
As we know that, the sum of any two sides of a triangle is greater than its third side, so given statement is not correct.
