A square has a side of 5.25 inches what is the diagonal?

Answer 1

To find the diagonal of a square, we can use the Pythagorean theorem, which states that the square of the hypotenuse (diagonal) of a right triangle is equal to the sum of the squares of the other two sides. In this case, the two sides of the square are both 5.25 inches. So, the diagonal can be calculated as follows: diagonal = √(5.25^2 + 5.25^2) = √(27.5625 + 27.5625) = √55.125 = approximately 7.42 inches.

Answer 2

You need to use the old Pythagorean theroem for this.... Which is a(squared) + b(squared) = c(squared) a and b being the sides of the square. 5.25(squared) + 5.25(squared) = 57.96. then you need to take the square root of this which is 7.61315 rounded to the closest 100,000 of an inch. Therefore the diagonal is 7.61315 inches.
