B. Writing an equation is the most useful
Step-by-step explanation:
We are required to find the best method which can be used to find the value of a variable.
Since, we know,
While writing an equation, we assign the dependent variable in terms of the independent variable.
These equations can be easily solved using the methods such as substitution and elimination.
Thus, they give the exact value of the variables.
While options A, C and D, does not give the value of the variables over the domain.
So, the best option useful to find the value of the variable is to write an equation.
That is, option B is the most useful.

I haven't learned this in a long time so not sure if I am typing this correctly. But it would be more probable to pick up a trapezoid than a square. I hope that helps. I have a great night!
