Answer 1

Answer:

The width of the room in the drawing is 30 cm.

Step-by-step explanation:

Given : The actual width of the classroom is 900 cm. If the scale chosen to make it drawing is 1:30.

To find : What will be the width of the room in the drawing?

Solution :

Let the width of the room in the drawing be 'x'.

The actual width of the classroom is 900 cm.

The scale chosen to make it drawing is 1 : 30.

According to question using proportionality,

$\frac{1}{30}=\frac{x}{900}$

$x=\frac{900}{30}$

$x=30$

Therefore, the width of the room in the drawing is 30 cm.
