technically it has rectangles, because a rectangle is two sets of parallel lines that connect at 90 degree angles.
cube
It is not possible to provide any kind of answer without information on the relationship - if any - between the triangle and the rectangle.
Rectangle: length x width triangle: (base x height)/2
No because the rectangle is a longer version of the cube and the cube is a shorter version of the rectangle.
square is rectangle as cube is to rectangular prism
triangle rectangle and cube
Any kind of triangle can be made in a rectangle.

There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
Rectangle: length x width triangle: (base x height)/2
The answer will depend on the relationship - if any - between the rectangle and the triangle.
No because the rectangle is a longer version of the cube and the cube is a shorter version of the rectangle.
square is rectangle as cube is to rectangular prism
Quadrant, Right angle triangle, cube, cuboid, rectangle, square and others
They are both geometric shapes
The main differences are. A triangle is three sided while a rectangle is four sided. The corners of a triangle can be any angle. All corners of a rectangle must be 90 degrees. This means that the left and right sides are parallel, and the top and bottom sides are parallel.
