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.
It is a cuboid. It is a cuboid.
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.
16 1x1 rectangles + 12 2x1 rectangles + 8 3x1 rectangles + 4 4x1 rectangles + 12 1x2 rectangles + 9 2x2 rectangles + 6 3x2 rectangles + 3 4x2 rectangles + 8 1x3 rectangles + 6 2x3 rectangles + 4 3x3 rectangles + 2 4x3 rectangles + 4 1x4 rectangles + 3 2x4 rectangles + 2 3x4 rectangles + 1 4x4 rectangle. A Grand Total of: 100 squares and rectangles. OR: A rectangle is formed by 2 horizontal lines and 2 vertical lines. There are 5 horizontal and 5 vertical lines so the number of rectangles is 5C2 * 5C2 = 10 * 10 = 100
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.
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.
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.
A hexagonal prism.
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 !
