Area = 0.5*(17+11)*9 = 126 square inches.
The height of the trapezoid is also needed to find its area which is as follows:- Area of a trapezoid = 0.5*(sum of bases or parallel sides)*height
Area of a trapezoid = 0.5*(sum of parallel sides)*height
Area of a trapezoid: 0.5*(sum of its parallel sides)*height
Area of a trapezoid = 0.5*(sum of parallel side)*height
Area of a trapezoid = 0.5*(sum of parallel sides)*height
Area of a trapezoid: 0.5*(sum of parallel sides)*height
Area of a trapezoid = 0.5*( sum of parallel sides)*height
Area of a trapezoid = 0.5*(sum of parallel sides)*height
Area of a trapezoid: 0.5*(sum of parallel sides)*height
Area of a trapezoid = 0.5*(sum of parallel sides)*height
The area of a trapezoid is equal to the height, multiplied by the average of the two widths.
If the lengths of the bases are also given then rearrange the area of the trapezoid formula so that the height is the subject.
