(1) 16 cm
(ii) 18 cm
(iii) 14 cm
(iv) 17 cm​

Answer 1

Step-by-step explanation:

difference of the third side must be greater than the difference of given length.

(9-7)=2cm

also the length of the third side must be less than the sum of the given lengths

(7+9)=16cm

so, the third side will be 14 cm which is greater than 2 cm and less than 16 cm
