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.

Quick Answer. A trapezoid has four sides and four vertices. A vertex is a corner of a polygon. According to Reference.com, a trapezoid is a quadrilateral plane figure that has two parallel sides and two non-parallel sides. All four-sided figures have four corners, or vertices. The perimeter of a trapezoid is determined the same way as that of a square or rectangle: the length of all four sides are added together. The area, however, is not determined the same way. For squares and rectangles, the area is determined by the formula area equals length times width.
