Aslice is made parallel to the base of a right rectangular pyramid, as shown. what is the area of the resulting two-dimensional cross-section? enter your answer in the box. cm²

From the figure, we are given with
length = 1 cm
width = 2 cm
The 2D cross section is a rectangle
The area is 
length x width
Substituting the given values,
Area = 1 cm (2 cm)
Area = 2 cm2

The area of the cross-sectional part is 2 cm square.

A rectangular pyramid is the pyramid with a triangular face on all sides having a top pick and a rectangular base.Trapezoidal prism is the extension of the quadrilateral which has only one pair. When you cut the pyramid from the top with a cross-section it is called a trapezoidal prism.

In the given figure the base of a rectangular pyramid has 2cm width and 4cm length. This pyramid has been cut by a section of a 2-dimensional cross-section having the length of 2 cm and the width of 1 cm.

To find out the area of the sectional part the cross-sectional part should be formulated,

Area of the cross section = Length X width

Hence, the area of the cross-sectional part is 2 cm square.
