New area = 256 so new side = sqrt 256 = 16 so old side = 12 (so old area = 144)
The area of a square of length m is m2 Accordingly, for a square of side length 6 length units = 62 square units. = 36 square units
i got the answer!
The length of a square is not determined by a formula, it is determined by measuring the square.
The length and width of a square are equal. Thus, find the square root of the area and the answer = length= width.
First, take the square root, to get the length of a side. Then (because of Pythagoras), multiply the length of the side by the square root of 2.First, take the square root, to get the length of a side.

256 divise by 4
(X+4)2=256 X+4=16 X=8 the sides of the original square is 8 cm
5cm because the square root of 121 is 11 and 5 plus 6 equals 11.
12 cm
256 = 162; 16 - 7 = 9 cm
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.
It is the square of the original number. If the original number represents a length, then the square of the original number represents an area of a square with side equal to the original number.
That depends what you want to calculate. To calculate the area, for a rectangular lot, just multiply length x width; in the special case of a square lot, this becomes length x length, or length square.
Let the original length of a side be d cm.Then (d + 5)2 = 144 = 122 : d + 5 = 12 : d = 12 - 5 = 7.The original square had a side length of 7 cm.
(4 times the square root of 'A') centimeters.
9 feet was the original side lengths
It becomes a bigger rectangle - possibly a square.
