Question: what is the formula for solving a trapezoid
Options:
Remind students that the area of a rectangle is base × height; for the rectangle formed from the original trapezoid, the base is ½( b1 + b2 ) and the height is h , so the area of the rectangle (and, consequently, of the trapezoid) is A = ½ h ( b1 + b2 )
