The total displacement of the person walking from point A to point B is 300 yards.
As shown in the figure we can conclude that the required method to calculate the total displacement is the Pythagoras theorem.
<h3>Pythagoras theorem in brief :</h3>
According to the Pythagorean Theorem, the square that represents the hypotenuse, or side of a right triangle that faces the right angle, is equal to the total of the squares on the triangle's legs.(or, in popular algebraic notation, 
).
<h3>Calculation: </h3>
Let,
a = 500
b= 300
Hence by using Pythagoras' theorem
Total displacement of the person = 
= 
= 
Thus the total displacement of the person from starting point is 300 yards.
