perfect answer will rewarded as brainliest​

Answer 1

Answer:

Since 90,91 are consecutive integers, all the numbers lying between 90² & 91² will be non-square numbers.

Total number of them = 91² - 90² - 1 = 181 - 1 = 180.

Answer 2

if there are two numbers n ^2 and (n + 1)^2then there are 2n non-perfect squares.

Here 90 is n

2n = 2 × 90 = 180

Therefore, there are 180 non-perfect squares
