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 trapezoid is equal to the height, multiplied by the average of the two widths.
Area of a trapezoid = 0.5*(sum of parallel sides)*height
If you take a regular four sided pyramid and chop off the top, parallel with the base, the left over piece would be a solid with four identical trapezoidal faces and a square top and bottom. The only name I know is 3-D trapezoid.
Never. It's impossible. If there are two acute angles, it means there have to be two obtuse angles, so three acute angles is impossible.
The altitude of a trapezoid bisects the bases of the trapezoid.
The average of the bases of a trapezoid is the median.
The bases on a trapezoid are the two lines that are parallel to each other. .............................. ....____base____...... .../ ...................\..... ../ .....................\.... ./_____base_____\... .............................
A trapezoid does not have three bases!
False.
The area of a trapezoid is 1/2 * (base 1 + base 2) * height, so the area of this trapezoid = 0.5*(3+7)*3 = 15 square yards
It is 5 inches.
They are parallel
The formula for area a is height X average of the two parallel bases of the trapezoid. In this instance, a = 3[(7 + 5)/2] = 18 square centimeters.
sometimes
The bases of a trapezoid are either of its parallel sides.
The parallel sides of a trapezoid are the two bases
