**11 squared**, (11)

^{2}, is the number you get when multiplying 11 times 11.

It can also be looked at as exponentiation involving the base 11 and the exponent 2.

The term is usually pronounced eleven times eleven or eleven squared.

The square of 11 is a perfect square because the number is the product of the two equal integers 11.

It can be written as 11 × 11 or in exponential form.

## What is 11 Squared?

A square is a flat shape with four equal sides; every angle is 90°.Hence, a square with side length 11 has an area of 121.

11 squared equals the sum of the first 11 odd numbers:

In addition, the number can be calculated from 10 squared using the following identity:

n

^{2}= (n − 1)

^{2}+ (n − 1) + n = (n − 1)

^{2}+ (2n − 1)

(11)

^{2}= 10

^{2}+ 10 + 11 = 10

^{2}+ 21 = 121

It can be also be computed from 10 squared with this identity:

n

^{2}= 2 x (n − 1)

^{2}− (n − 2)

^{2}+ 2

(11)

^{2}= 2 x 10

^{2}– 9

^{2}+ 2 = 2 x 100 – 81 + 2 = 121

The difference between the perfect square of 11 and its predecessor, 10, can be calculated with the identity n

^{2}− (n − 1)

^{2}= 2n − 1:

2 x 11 – 1 = 21 = (11)

^{2}– 10

^{2}= 121 – 100 = 21

11 is odd, and the square numbers of odd numbers are also odd: (2n + 1)

^{2}= 4 × (n

^{2}+ n) + 1.

Squares of odd numbers like 11 are of the form 8n + 1, because (2n + 1)

^{2}= 4n × (n + 1) + 1;

n × (n + 1) is an even number.

If you want to calculate the square of any number, not only integers like 11, you can use our calculator above.
