Question

Special-effects artists often use scale models.the actual height of a velociraptor is estimated to have been approximately 2 ft.an artist draws the dinosaur with a height of 4 in. on paper.
a. what would be an appropriate scale for a model of the velociraptor?
b. the same scale is used for a model of a tyrannosaurus, whose actual height was 16 ft.what is the height of the model?

Answer 1

we know that

part A)
[scale]=[model height]/[actual height]
[scale]=[4 in]/[2 ft]=2 in/ft
that means
(2 in) in the model is -------------> (1 ft) in the actual

part B) 
[actual height]=16 ft     [model height]=?    [scale]=2 in/ft

[scale]=[model]/[actual height]
[model height]=[scale]*[actual height]
[model height]=[2]*[16]=32 in
the answer part B) is 32 in
