In ∆ABC, AB=2.5cm and BC=6cm. Then, the length of AC cannot be
It is given in the question that,
In
AB = 2.5 cm
BC = 6 cm
We know that, the length of a side must be less than the sum of the other two sides
Let us assume the side of AC be x cm
∴ x < 2.5 + 6
x < 8.5
Also, we know that the length of a side must be greater then the difference between the other two sides
∴ x > 6 – 2.5
x > 3.5
Hence, the limits of the value of x is
3.5 < x < 8.5
∴ It is clear the length of AC cannot be 3.4 cm
Hence, option (A) is correct
