Find the area of each of these trapezoids. Show all of your steps.

  1. A trapezoid with horizontal parallel bases: bottom is16 cm, and top is 12 cm, with left side, 5.4 cm. A right triangle is created, by a dashed line segment, of 5 cm, drawn from the upper left vertex, to the base at right angles.

    The equation for the area of a trapezoid is:

    Locate the different parts of the equation on the trapezoid.
    Then substitute the values and solve the equation to calculate the area.

  1. A trapezoid with horizontal parallel bases: bottom is 12 in, and top is 5 in, and right side is 5.3 inches. A line, labeled 4 in, perpendicular to both bases, connects the bases.
