20 is between the perfect squares .

Answer 1

To find out between which two perfect squares the number 20 lies, we can look at the perfect squares close to 20.

The perfect squares we have are:

• \(4^2 = 16\)
• \(5^2 = 25\)

Since \(16 < 20 < 25\), we can conclude that:

20 is between the perfect squares 16 and 25.
