1. Click on the link to use the interactive tool to create a trapezoid with the following dimensions:
height - 6 units
base AB - 10 units
base CD - 12 units
2.Look at the blue text with the calculation of area.
3.Click on the box that says "freeze dimensions". Notice how the area does not change in the displayed formula. The area depends only on the height and base lengths, so as you can see, there are many trapezoids with a given set of dimensions which all have the same area.
4.What is the formula for area of a trapezoid? Write the formula and make a trapezoid with the same measurements with grid paper and paste it into your math journal.
