The plot for a proposed new city hall plaza is 120 feet long by 90 feet wide. A scale model for the plaza must fit in an area that is 10 feet square.

Question

If the largest possible model is built in that area, what will be the maximum possible width for the scale model?

 

A) 2/15 feet

 

B) 1 and 1/3 ft

 

C) 7and 1/2 feet

 

D) 13 and 1/3 ft

 

Answer 1

Actual size 120 feet X 90 feet

 

If the length (120) is scaled to 10 feet, then the factor is 1/12

 

the "scaled width" will be 90 / 12 = 7.5 feet
