±√121 what is the answer

±√121 = ±11 (11, -11)

Step-by-step explanation:

1.First, find two equal numbers multiplied by each other to get 121:

This will be 11×11, so the answer for the square root is +11 or -11.

2. Or you can find the square root of a number using this method:

draw a line splitting two sides from each other.then, write the number inside the square root on the left side of the line.after that, on the right side, write a number that can be divided by 121 ( it should be a whole number and a prime number).write the answer to the division on the left side of the line.next, rewrite the two steps above by writing a number that can be divided by the answer of the division.stop writing the number when you get to number one on the left and right sides.finally, match every two equal number together to make it on the number and multiply them together to get the answer for the square root.you can understand it more from the picture below, I also did another example for this method.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
