The area of a rectangle can be calculated by multiplying one side length by another side length (or in other words, length and width). Since a square is also a rectangle, to find the area, we need to multiply 11 by 11, which is 121. Hope that helps!

121 is, itself, a perfect square.

Width = 110 cm Length = 121 cm Height = 1.0909 cm

A perfect square is a whole number multiplied by itself. 121 = 11*11

Yes. 121 = 11 x 11.

121 square feet. Just multiply length by width - the answer is the square footage.

121 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.

There are an infinite number of answers to this question, as you can take any number greater than zero and less than 21780, divide it into 21780, and have a valid answer. You can express the relationship as: l = 21780 ft2 / w So if the width is half a foot, then the length would be 43560 feet. On the other hand, if the width is 180 feet, then it's length would be 121 feet.

No.... Number nearest to 124 which i a perfect square is 121 & then 144

A minimum of 121 square feet. Just multiply length by width - the answer is the square footage.

1, 11, and 121. (This number has an odd number of factors because it is a perfect square: 11 * 11 = 121.)

The length of each side is 11. To get the length you only have to do the square root of 121. Prove your answer by multiplying side by side.

s2, the side length squared = area = 121 s = square root 121 = 11 length total = perimeter = sum of all 4 sides = 4s = 44 cm

11 squared is 121

The new square has an area of 121, so the length of a side is the square root of 121, or 11. So the length of the side of the old square was 10.

No, it is not. For it to be a perfect square, the square root of it would have to be an integer, but √120 ≈ 10.954. 100 and 121 are perfect squares nearest to 120. ■

Since no integer multiplied by itself can yield 111, it is not a perfect square. 121, however, is a perfect square. Its square root is 11.
