If you restrict yourself to integers, there are four.
There are infinitely many. Choose ANY positive number for the width; in that case, the length will be 64 divided by the width.

Thee different rectangles with an area of 12 square units are 3 by 4, 2 by 6 and 1 by 12.
area = 144 square units perimeter = 48 units
Squares are rectangles. Draw a 2 unit square.

That depends on the rectangle! You can have different rectangles with the same area, but with different perimeters.
Thee different rectangles with an area of 12 square units are 3 by 4, 2 by 6 and 1 by 12.
Area of a rectangle in square units = length*width
area = 144 square units perimeter = 48 units
1 unit x 64 units 2 units x 32 units 3 units x 64/3 = 21.3... units 4 units x 16 units 5 units x 64/5 = 12.8 units 6 units x 64/6 = 10.66.. units And you could do 1.1 x , 1.2 x etc
3 or 6, depending on whether rectangles rotated through 90 degrees are counted as different. The rectangles are 1x12, 2x6 3x4 and their rotated versions: 4x3, 6x2 and 12x1.
Infinitely many.

A = LW 64 = 64 * 1 or 1 * 64 64= 32 * 2 or 2 * 32 64 = 16 * 4 or 4 * 16
