What is the square root of 121?

  1. 10

  2. 11

  3. 12

  4. 9

The correct answer is: 11

The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, to find the square root of 121, we need to identify a number that, when squared (multiplied by itself), equals 121. The number 11 fits this requirement perfectly because 11 multiplied by 11 is 121 (11 x 11 = 121). Therefore, 11 is the square root of 121. This confirms that the answer is correct. In contrast, the other choices do not yield 121 when squared: - Ten multiplied by ten equals 100. - Twelve multiplied by twelve equals 144. - Nine multiplied by nine equals 81. None of these options matches the original value of 121, reinforcing that 11 is indeed the correct answer.
