Answer:

Explanation:
The polygon is a trapezoid on its side. 
The formula for the area of a trapezoid is 
A = ½(a + b)h, 
where a and b are the lengths of the parallel sides and h is the distance between them. 
AD = a = 2 – (-2) = 2 + 2 = 4 units 
BC = b = 2 – (-5) = 2 + 5 = 7 units 
AB = h = 3 – (-4) = 3 + 4 = 7 units 
A = ½(4 + 7) × 7 = ½ × 11 × 7 = 38.5 units²
