Area of the modest sized house that is given in the question is = 155 m^2 Now, we already know that 1 meter = 10 decimeter So 1 m^2 = 10^2 square decimeter 155 m^2 = 155 x (10)^2 square decimeter = 155 x 100 square decimeter = 15500 square decimeter So the area of the house in question in decimeter square is 15500 decimeter square.
