Answer:

Scale for drawing is 1:350

Step-by-step explanation:

scale is ratio of size of drawing and size of actual object for which the drawing is made

it is represented as

scale = size of drawing : size of actual object

given

length of model in drawing = 2cm

length of bedroom in reality = 7 meter

since there are two units we meter and cm

we convert both in same unit that is cm for simpler calculation

1 meter = 100 cm

7 meter = 7*100 cm = 700cm

length of bedroom in reality = 7 meter = 700 cm

Thus,

scale for drawing = length of drawing/ actual length of bedroom

scale for drawing = 2 cm : 700cm = 1:350

Scale for drawing is 1:350
