The answer is C, 120 centimetres
Explaination:
You have to use the Pythagoras theorem
13 squared = 169
7 squared = 49
Since it’s the shorter side we are trying to find we subtract.
169 - 49= 120 cm

Answer:

C-120cm

Step-by-step explanation:

using pythagoras theorem to solve it

13^2=b^2+7^2

b^2=13^2-7^2

b^2=169-49

b^2=120

b=√120

b=10.95
