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. Multiply this by the height (distance between the parallel sides. Calculating the Area of a Trapezoid.
You can find the perimeter of the trapezoid if you are missing the base measurement but have the measurements of the other three sides and the two inner base angles. You will need to visually split the trapezoid into three parts: a rectangle at the center and two triangles at either end.
