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)

A. 26+26= 52116-52=6464/2=32b. add the lengths that you already have for he rectangle. you then subtract the amount you got from your lengths from the perimeter. since you have 2/4 of the lengths, you need to find the other two, dividing 64 by 2 will give you your other two lengths.
