In the next section we elaborate on what is 17 squared and there you can also find our calculator.

## What is 17 Squared?

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

Hence, a square with side length 17 has an area of 289.

17 squared equals the sum of the first 17 odd numbers:

In addition, the number can be calculated from 16 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
(17)2 = 162 + 16 + 17 = 162 + 33 = 289

It can be also be computed from 16 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
(17)2 = 2 x 162 – 152 + 2 = 2 x 256 – 225 + 2 = 289

The difference between the perfect square of 17 and its predecessor, 16, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 17 – 1 = 33 = (17)2 – 162 = 289 – 256 = 33

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

Squares of odd numbers like 17 are of the form 8n + 1, because (2n + 1)2 = 4n × (n + 1) + 1;
n × (n + 1) is an even number.
