Yes, it can because a 3 by 6 rectangle has the perimeter of 18 and has the area of 18! :)
Yes. Say there are two rectangles, both with perimeter of 20. One of the rectangles is a 2 by 8 rectangle. The area of this rectangle is 2 x 8 which is 16. The other rectangle is a 4 by 6 rectangle. It has an area of 4 x 6 which is 24.

126 rectangles. 1 Strip of 6 equals 21 rectangles, multiply by 1 strip of 3 which makes 6, is 126 rectangles, all in one big rectangle.
A larger rectangle whose width is twice as long as one of the smaller rectangles and whose length is three times that of one of the smaller rectangles.
In a 4 by 4 grid, there are 16 squares (1x1 squares), 9 rectangles that are 2x1, 6 rectangles that are 3x1, 4 rectangles that are 2x2, and 1 rectangle that is 4x4. Therefore, in total, there are 16 squares and 20 rectangles in a 4 by 4 grid.
No rectangle can have 6 sides. Rectangles by definition have 4 sides. ------------ A 6-sided rectangular solid, on the other hand, has... let's see, could it be six?
I can give the width of one of the rectangles. The first rectangle of area 15 cm2 and length of 5 cm has width of 3 cm. It is impossible to know the width of the other rectangle of area 60 cm2. However, if you had said that the two rectangles were similar, then the dimensions of the second rectangle would be 10 cm X 6 cm. But you didn't say that the two rectangles were similar; so there are infinite possibilities of what the dimensions of the second rectangle might be.
2 rectangles. Put two toothpicks on 2 sides and one on the other side, and that uses 6 toothpicks and if you make another rectangle like that you make 2 rectangles.

To find the number of rectangles with an area of 36 cm², we need to consider the pairs of positive integer factors of 36. The pairs are (1, 36), (2, 18), (3, 12), (4, 9), and (6, 6), resulting in 5 unique combinations. Since the order of the dimensions does not matter (e.g., a rectangle of dimensions 2 cm by 18 cm is the same as 18 cm by 2 cm), there are 5 distinct rectangles that can be drawn with an area of 36 cm².
That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !
