Each of them is 14.14 inches long. (rounded)

A square with a 30-inch diagonal measurement has sides of 21.21 inches in length.

Using Pythagoras each side is 26*sq rt of 2 which is 1352 when squared. So area of the square is 1352 square inches

To find the diagonal, use the Pythagorean theorem by drawing a diagonal through the square. You then have two sides that should equal the hypotenuse ( or diagonal). The equation should look like 8^2 + 8^2 = h^2. or 64+64= h. 128=h take the square root of 128 and you have your answer. the answer should be around 11.

The diagonal is 221.2 inches long.
