String A is 140, String B is 110, String C is 50
To find the length of string C, substitute the expressions for A and B into the equation for the total length of all three strings. Simplify the equation to find the value of C. The length of string C is 30cm. ;
The length of string C is 50 cm. This was found by setting up equations based on the relationships between the lengths of the three strings and solving for C. After substituting and simplifying, we determined the result.
