32. The correct answer is (D). Points (21,21) and (2,21) connect to form a horizontal

line segment of length 3. Similarly, points (2,3) and (25,3) connect to form a horizontal

line segment of length 7. Since the two segments are parallel, the resulting

quadrilateral is a trapezoid. The vertical distance between the two parallel segments

is 4. Apply the formula for a trapezoid’s area (AB and CD represent the two parallel

segments, and h is the quadrilateral’s height):

You can also plot the quadrilateral on the grid, divide it into a right isosceles triangle

and one rectangle, then calculate the area of each one. (The rectangle’s area is 12, and

the triangle’s area is 8.)
