What is 722 Squared?

A square is a flat shape with four equal sides; every angle is 90°.

Hence, a square with side length 722 has an area of 521,284.

722 squared equals the sum of the first 722 odd numbers:

In addition, the number can be calculated from 721 squared using the following identity:

n² = (n − 1)² + (n − 1) + n = (n − 1)² + (2n − 1)
(722)² = 721² + 721 + 722 = 721² + 1443 = 521,284

It can be also be computed from 721 squared with this identity:

n² = 2 x (n − 1)² − (n − 2)² + 2
(722)² = 2 x 721² – 720² + 2 = 2 x 519841 – 518400 + 2 = 521,284

The difference between the perfect square of 722 and its predecessor, 721, can be calculated with the identity n² − (n − 1)² = 2n − 1:

2 x 722 – 1 = 1443 = (722)² – 721² = 521,284 – 519841 = 1443

722 is even, and the square numbers of even numbers are also even: (2n)² = 4n².

Squares of even numbers like 722 are divisible by 4 for

= n².
