a. 9 and 10

b. 11 and 12

c. 14 and 15

d. 12 and 13

Answer 1

12 and 13

Explanation:

We are required to find the two consecutive integers among which the square root of 151 lies. In order to solve this problem , let us first guess the nearest perfect squares to 151. The 144 is the perfect square which comes before 151 and 169 is the perfect square which comes after 151. Hence the square roots of 144 and 169 will be our integers.

Square root of 144 = 12 and the Square root of 169 = 13

Hence our answer is 12 and 13.

Answer 2

12^2 = 144
13^2 = 169
151 is between 144 and 169.
Therefore, square root of 151 is between 12 and 13.
