Question

PLEASE HELP!!! What is the length of the diagonal of the square??

Answer 1

Since it is a right triangle, we can apply the Pythagorean theorem.

The square of the hypotenuse is equal to the sum of the squares of the sides.

We'll call H the hypotenuse and L to the side.

H² = L² + L² = 2L²

H² = 2x11²

$H = \sqrt{2x11^{2}}= 11\sqrt{2}$

ANSWER = F) = $Diagonal= 11\sqrt{2}$
