The shape of the cross section formed from slicing the pyramid is called; a triangle
<h3>What is the Pyramid's Cross Section? </h3>
We are told that it is a pyramid with a base that is a pentagon with all sides the same length.
Now, the Pyramid's ap-ex is usually constructed by isosceles triangles. Thus, when they are sliced from its ap-ex to from the vertex, in the cross section a triangle will be formed, This triangle will be an isosceles triangle.
In conclusion, the shape of the cross section formed from slicing the pyramid is a triangle.

<span>A = l x w
Since
l = 3w
Substitute the l with 3w
The formula will be
A = 3w + w
A = 4w
An example:
The
given known values are: Length of 4 cm Width is unknown Perimeter is 34
cm Find the dimensions of the rectangle. Since the geometric formula
for perimeter is: </span>
P= 2 (l + w)
L = 2w – 4 cm
W =?
Derivation and solution:
34 = 2 (2w - 4) + 2w <span>
34 = 4w – 8 + 2w</span>
42 = 6w 42/6 = w
W = 7 cm
34 = 2l + 2(7)
34 = 2l + 14
2l = 34 – 14
2l = 20
L = 20/2
L = 10 cm<span> <span>
