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
