A trapezoid has one surface and its surface area in square units is 0.5*(sum of parallel sides)*height
You always use square units when measuring area.
38 square units
120 square units
trapezoid
3.14x2=6.28
Area of trapezoid: 0.5*(5+7)*3 = 18 square units

Area of a trapezoid in square units = 0.5*(sum of parallel sides)*height
Area in square units = 0.5*(sum of parallel sides)*height
Do you mean the area of a trapezoid if so then the formula is:- Area measured in square units = 0.5*(sum of the parallel sides)*height
There are many possibilities as for example: 0.5*(3+9)*8 = 48 square units
