256 divise by 4
12 cm
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.
The length and width of a square by definition are of equal length. The area (A) of a square = d2, where d is the length of one side. If the area is known, then the length of the side of a square, d = √A (square root of A).
9² = 81 square units.Area= length*length= 9*9= 81 unit square
8100 square units
(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
New area = 256 so new side = sqrt 256 = 16 so old side = 12 (so old area = 144)
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.
