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.

trapezoid, closed plane figure bounded by four line segments, or sides, two of which are parallel and two of which are nonparallel. The parallel sides of a trapezoid are called bases and the nonparallel sides legs; in an isosceles trapezoid the legs are of equal length. The median of a trapezoid is the line segment connecting the midpoints of the legs; it is parallel to the bases and equal to half the sum of their lengths.
