<u><em>Answer:</em></u>
The total length of the two strings is meters
<u><em>Explanation:</em></u>
<u>Before beginning, remember the following:</u>
<u>Now, for the given problem:</u>
<u>We are given that:</u>
Length of string A = meters
Length of string B = meters
<u>To get their sum, we follow these steps:</u>
a. Make the denominator for the two fractions the same
b. Add the numerators
c. Simplify
<u>This is done as follows:</u>
For the given fractions, the common denominator will be 4×6 = 24
<u>Therefore:</u>
String A = m and String B =
m
<u>Now, we add:</u>
<u>Finally, we simplify:</u>
obtained by dividing both numerator and denominator by 2
