What is 981 Squared?

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

Hence, a square with side length 981 has an area of 962,361.

981 squared equals the sum of the first 981 odd numbers:

In addition, the number can be calculated from 980 squared using the following identity:

n² = (n − 1)² + (n − 1) + n = (n − 1)² + (2n − 1)
(981)² = 980² + 980 + 981 = 980² + 1961 = 962,361

It can be also be computed from 980 squared with this identity:

n² = 2 x (n − 1)² − (n − 2)² + 2
(981)² = 2 x 980² – 979² + 2 = 2 x 960400 – 958441 + 2 = 962,361

The difference between the perfect square of 981 and its predecessor, 980, can be calculated with the identity n² − (n − 1)² = 2n − 1:

2 x 981 – 1 = 1961 = (981)² – 980² = 962,361 – 960400 = 1961

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

Squares of odd numbers like 981 are of the form 8n + 1, because (2n + 1)² = 4n × (n + 1) + 1;
n × (n + 1) is an even number.
