Sketch a diagram to help comprehend the situation. Plot the three given
points and connect them to make two of the sides of the trapezoid:
PICTURE IT
Whenever you come to a geometry question with no figure, a sketch
can make an abstract-looking problem concrete and manageable.If points (6, 0), (0, 0), (0, 2), and (a, 2) are consecutive vertices of a
trapezoid of area 7.5, what is the value of a?
