Solution:

In a blueprint of a room, an architect has shown the height of the room as 33 cm.

The actual height of the room is 330 cm.

We have to find the scale used by her.

We know, Scale of map = size drawn/actual size

Given, size drawn = 33 cm

Actual size = 330 cm

So, scale = 33/330

= 1/10

Therefore, the scale is 1 : 10.
