What is 72 Squared?A square is a flat shape with four equal sides; every angle is 90°.
Hence, a square with side length 72 has an area of 5,184.
72 squared equals the sum of the first 72 odd numbers:
In addition, the number can be calculated from 71 squared using the following identity:
n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
(72)2 = 712 + 71 + 72 = 712 + 143 = 5,184
It can be also be computed from 71 squared with this identity:
n2 = 2 x (n − 1)2 − (n − 2)2 + 2
(72)2 = 2 x 712 – 702 + 2 = 2 x 5041 – 4900 + 2 = 5,184
The difference between the perfect square of 72 and its predecessor, 71, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:
2 x 72 – 1 = 143 = (72)2 – 712 = 5,184 – 5041 = 143
72 is even, and the square numbers of even numbers are also even: (2n)2 = 4n2.
