Question

Which is a perfect square between 49 and 121

Answer 1

Answer:

49 and 121 are perfect squares.

Step-by-step explanation:

By definition, a perfect square is a number that is generated by multiplying two equal integers by each other.

7 ×7 or 7² = 49

11 × 11 or 11² = 121

Another way of checking whether a given number is a perfect square:

Finding the number’s square root. If the square root of a number is a whole number, then the number is a perfect square.

$\sqrt{49} = 7$

$\sqrt{121} = 11$

Therefore, 49 and 121 are both perfect squares.
