The equation used for finding the length of Harold's bridge will be 3H-7M=0 Length will be H = 1/√2
<h3>What is an equation?</h3>
The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
Here we have the following data:-
Matthew's bridge length is
1(1/2)=3/2
Now we have that Harold made a bridge that was 2 1/3 times as long as Matthew’s. From this data the equation will be:-

The equation used for finding the length of Harold's bridge will be 3G-7M=0 Length will be H = 1/√2
