Answer 2

Answer:

The actual height of the buiding is option C 36m

Step-by-step explanation:

• Scale is defined as the ratio of the distance in the map to the original distance.
• For the model, it can be the ratio of the model dimensions to the original dimensions.
• The scale given for the model=$\frac{1}{300}$
• Height of building in the model=12 cm
• Actual height of the building is given by

       $Scale=\frac{Model\ dimension}{Original \ Dimension}$

      $\frac{1}{300} =\frac{12}{x}\\ x=12\times300\\x=3600cm$

• Height in m =36m
