a) a room 14 feet long; 1 inch = 6 feet
To find the length of each object on the scale drawing we make a proportion using the given information
6 feet = 1 inch , 14 feet = x inches
=

=

Cross multiply it,
14 = 6x
divide by 6 on both sides
So x = 2.3 inches
b) a tower 40 meters tall; 0.8 centimeter = 1 meter.
Lets make a proportion using given information
1 meter =0.8 centimeter , 40 meters = x centimeter


40 * 0.8 = 1x
x= 32 centimeter
