Given:

d = 13.3\ in

w = 11.3\ in

d=\sqrt{w^2+h^2}

To find:

The value of h.

Solution:

We have,

d=\sqrt{w^2+h^2}

Substituting d = 13.3, w = 11.3, we get

13.3=\sqrt{11.3^2+h^2}

Taking square on both sides.

176.89=127.69+h^2

176.89-127.69=h^2

49.2=h^2

Taking square root on both sides, we get

\pm 7.01427=h

h\approx \pm 7

Height cannot be negative so h=7\ in.

Therefore, the correct option is A.
