Step-by-step explanation:
- 20+13 is not equal to 7
- 13+7=20
- 20+7 is not equal to 13
- So when we add these numbers we should get same answer but we did not get that.
- So it is impossible to construct it

Answer:
Because the sum of two sides of the triangle should be greater than the third side. [TRIANGLE INEQUALITY PROPERTY]
Side 1= 20cm
Side 2= 13cm
Side 3= 7cm
20+13= 33cm> 7cm
20+7= 27cm> 13cm
13+7= 20cm=20cm
Thus, Rohan couldn't construct this triangle.
