To find:
    • The ratio of the area of triangle DEC to the area of rectangle ABCD

Approach and Working:
    • The area of the triangle DEC = ½ x DC x AD = ½ x 5y x 3x
    • The area of the rectangle ABCD = DC x AD= 5y x 3x
    • Hence, the ratio = (½ x 5y x 3x): (5y x 3x) = ½: 1 = 1: 2

Hence, the correct answer is option D.
