Answer:
25 square units
Step-by-step explanation:
Draw a segment from point B to point (3, 0). Call point (3, 0) point E.
Now you have a trapezoid, ABED, with parallel sides AD and BE, and a triangle, BEC. We find the area of the trapezoid and the area of the triangle and add then together.
total area = area of trapezoid + area of triangle
total area = (B + b)h/2 + bh/2
total area = (4 + 3)(6)/2 + 2(4)/2
total area = 21 + 4
total area = 25
