Square diagonal

Calculate the length of diagonal of the square with side a = 23 cm.

Result

d =  32.53 cm

Solution:

Leave us a comment of example and its solution (i.e. if it is still somewhat unclear...):

Math student
Why do you need to do
d squared = a squared + a squared

Dr Math
just  simple Pythagorean therorem

To solve this example are needed these knowledge from mathematics:

Pythagorean theorem is the base for the right triangle calculator.
