Cylinder
The answer depends on the relative sizes of these shapes.
1 method is to multiply length times the width and the 2 method is to divide the rectangle into triangles and find the area of one of the triangles and multiply the area by two.
In 3d a hexagonal pyramid. In 2d, two hexagons. Or a six-pointed star (like a Star of David), a parallelogram plus lots more possibilities
A prism.
Almost any 2D/3D shape has more than one vertex. Triangles, squares, rectangles etc. etc.
circle based rectangle
A Triangular Pyramid has 4 triangles and 1 square.
a hexagon * * * * * Depending on the shape and sizes of the triangles and where they are attached, you can also get a kite, a rectangle, a parallelogram, a decagon, octagon, pentagon.
The answer would be i think a rectangular pyramid. Not sure tho.
if u are talking about polygons then u would get a hexagon
there are 4 triangles and 1 rectangle in an rectangular pyramid
You get two congruent right triangles when you divide a rectangle diagonally. (This is one way to show that the area of each of those triangles is 1/2*base*height. Rectangle area = (4 in)(8 in) = 32 in2. Triangle area = (1/2)(4 in)(8 in) = 16 in2.)
A pyramid.
Cylinder
A rectangular-based pyramid.
That is one type of pyramid.
