Question

solve................

Answer 1

This is not possible since the Triangular inequality law says that the sum of any two sides of a traingle should be greater than the third side.
But here the sum of the length of sides is (3.1+2.5) = 5.6
Which is less than 5.7 that's the length of the third side.
Hence, it's not possible to sketch this triangle on a Cartesian real plane

Answer 2

It is not possible to sketch this triangle because to form a triangle, the difference of two greater sides of a triangle must be lesser than the third side.
Here, 5.7 - 3.1 = 2.6 > 2.5
Hence its not possible
