The area of a trapezoid is equal to the height, multiplied by the average of the two widths.
Work out each figure separately then add them together: Area of a trapezoid = 0.5*(sum of parallel bases)*height Area of a rectangle = length*height
The area of a circle can be found with the formula (pi)r^2
Area of a trapezoid = 0.5*(sum of parallel sides)*height
Area of a trapezoid in square units = 0.5*(sum of parallel sides)*height Perimeter = sum of its 4 sides
