To find the length of side AD, we can use the Pythagorean theorem since ABCD is a quadrilateral.

Let's consider triangle ABD. Using the Pythagorean theorem, we have:

AD^2 = AB^2 + BD^2

Since AB = 11 inches and BC = 4 inches, we can find BD using the Pythagorean theorem in triangle BCD:

BD^2 = BC^2 + CD^2
BD^2 = 4^2 + CD^2
BD^2 = 16 + CD^2

Now, substituting BD^2 into the equation for triangle ABD, we get:

AD^2 = 11^2 + (16 + CD^2)
AD^2 = 121 + 16 + CD^2
AD^2 = 137 + CD^2

However, we do not have enough information to directly find the length of side AD without knowing the length of CD or the angle measures in the quadrilateral. So the length of side AD cannot be determined with the given information.
