No, the new house is not congruent to the original house.
To determine congruency, we need to compare the corresponding sides and angles of both figures.
In the original house, the side lengths are:
AB = 4 units
BC = 6 units
CD = 4 units
DA = 2 units
In the new house, the side lengths are doubled:
AB' = 8 units
BC' = 12 units
CD' = 8 units
DA' = 4 units
Since the side lengths of the new house are double that of the original house, they do not match the original figure, and hence the new house is not congruent to the original one.
