To find the unknown side of the right triangle, we can use the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the two sides given are 3 yards and 4 yards. Let's denote the unknown side as x.

So, using the Pythagorean Theorem:

x^2 = 3^2 + 4^2
x^2 = 9 + 16
x^2 = 25
x = √25
x = 5

Therefore, the unknown side of the right triangle is 5 yards.
