What is 169 Squared?

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

Hence, a square with side length 169 has an area of 28,561.

169 squared equals the sum of the first 169 odd numbers:

In addition, the number can be calculated from 168 squared using the following identity:

n² = (n − 1)² + (n − 1) + n = (n − 1)² + (2n − 1)
(169)² = 168² + 168 + 169 = 168² + 337 = 28,561

It can be also be computed from 168 squared with this identity:

n² = 2 x (n − 1)² − (n − 2)² + 2
(169)² = 2 x 168² – 167² + 2 = 2 x 28224 – 27889 + 2 = 28,561

The difference between the perfect square of 169 and its predecessor, 168, can be calculated with the identity n² − (n − 1)² = 2n − 1:

2 x 169 – 1 = 337 = (169)² – 168² = 28,561 – 28224 = 337

169 is odd, and the square numbers of odd numbers are also odd: (2n + 1)² = 4 × (n² + n) + 1.

Squares of odd numbers like 169 are of the form 8n + 1, because (2n + 1)² = 4n × (n + 1) + 1;
n × (n + 1) is an even number.
