Carla made a scale drawing of a classroom. The length of the classroom in the drawing is 5in. The actual length is 40ft. What scale did Carla use for her drawing?

1/96

Step-by-step explanation:

scale is

a model cannot be as same size as that of actual object,

hence objects are scales down to some value so that its model can be comfortably made.

scale is generally ratio of length of drawing and actual length of object

scale = length of drawing / actual length of object.

Given

length of classroom drawing = 5in

actual length of classroom = 40 ft

as unit of drawing and actual classroom is different lets make unit of class smilar to that of drawing that is in inches

we know

1 feet = 12 inches

thus 40 feet = 12*40 inches = 480 inches

thus,

actual length of classroom in inches = 480 inches

scale used by Carla = length of drawing / actual length of classroom

= 5 inches/480 inches = 1/96 (answer)
