Answer:
Option D, 63 cm
Explanation:
The scale of model is of local park is [tex]1:21[/tex]
This means that each dimension of the model is 21 times smaller than the actual park (to be developed in future)
Given -
Depth of the pond [tex]= 3[/tex] centi meter
Depth of the real pond will be 21 times of the depth of the model.
Thus , real pond's depth is equal to
[tex]= 3 * 21\\= 63[/tex] cm
Hence, option D is correct
