Draw an isosceles trapezoid (a trapezoid with two equal, non-parallel sides). Label the top base cm and the height cm. If the area of this trapezoid is square cm, what is the length of the other base? You may find it helpful to use the 5‑D Process to write an equation to solve.  

A trapezoid, with the right and left sides of the same length. Top side labeled 6 cm. A dashed line from the top left vertex to the bottom side at right angles, is labeled 4 cm.

Note: Figure not necessarily drawn to scale.

Try different values to solve for the other base.

cm. Be sure to follow the Order of Operations.
