2.2 cm, 3 cm, 7 cm
3.3 cm. 4 cm. 5 cm
4.3 cm. 5 cm. 7 cm​

Answer 1

Answer:

here the property to be used is : sum of two side of a triangle is more than the third side

1. 1.3cm,4cm,7cm

1.3+4=7

5.3=7

LHS<RHS

triangle is not possible

2. 2.2cm,3cm,7cm

2.2+3=7

5.2=7

LHS<RHS

so triangle is not possible

3. 3.3cm,4cm,5cm

3.3+4=5

7.3=5

LHS>RHS

so triangle is possible

4. 4.3cm,5cm,7cm

4.3+5=7

9.3=7

LHS>RHS

so triangle is possible
