How to use Clay Bars: Clay Bars should always be used on freshly washed, clean surfaces. Dirt on the surface could cause scratches. Caution: Use only as directed and with an approved Clay Bar Lubricant to reduce friction between the Clay Bar and the vehicle's surface. Work on areas of about three square feet.
A trapezoid is a quadrilateral (has 4 sides) and has only one pair of sides parallel. How to determine the area of a trapezoid: Add the lengths of the 2 parallel sides divide by 2 to get the average length of the parallel sides.Multiply this by the height (distance between the parallel sides.Calculating the Area of a Trapezoid.ow to determine the area of a trapezoid: Add the lengths of the 2 parallel sides divide by 2 to get the average length of the parallel sides.

Students discover the area formula for trapezoids, as well as explore alternative methods for calculating the area of a trapezoid. Prior to this lesson, students will need experience in measuring rectangles and triangles and calculating their areas. Students will also need to be able to identify trapezoids.
