Question 937835: Looking for help to solve the following geometry problem. One side of a triangle is 18 cm. Inside the triangle, a segment is drawn parallel to the 18 cm side, forming a trapezoid whose area is 1/3 that of the original triangle. Find the length of this segment.

The segment splits the original triangle into two pieces:
a trapezoid and a smaller top triangle.

is the scaling factor between the two triangles
because the area of the top triangle is
of the area of the original triangle.
