There is no such shape.
If a regular 2D shape - a square or rectangle - times the length by the width to get the area.If the shape is irregular than drawing squares inside the shape will aid in finding the total area. There are other ways worth studying.The area of a right-angle triangle is half the size of a rectangle or square. The triangle's base x side will give the area of the rectangle or square. Dividing by 2 will halve the rectangle or square, so giving the area of the right-angle triangle.
Simply assemble the triangles in to a rectangle.
Simple. A triangle is a 2-dimensional object and therefore its volume is always 0.
cube

Irregular shapes have NO lines of symmetry and all the sides are not the same. A regular shape WILL have lines of symmetry and all the sides are the same. * * * * * Wrong! A kite, for example, is an irregular but it has reflective symmetry. A parallelogram is an irregular quadrilateral but has rotational symmetry.
The 2 types of shapes are the geometric shapes and the organic shapes. Geometric shapes are ones that can be described using mathematical formulas. They also have specific math names. Geometric shapes: Circle, Square, Rectangle, Triangle, etc. Organic shapes are irregular and uneven.
Divide polygon into rectangles, then use area formula for rectangle: Area = (high a + high b) / 2 x length c If polygon contains triangle, then triangle can be considered as rectangle with one of its side length is close to zero.
If the triangles are congruent then it is a triangular-based prism.
No because a rectangle is a 2 dimensional shape
