Answer 2

Answer:

The size of the object is 12cm.

Explanation:

According to the question,

the size of the image is about 36 cm and it is about 3 times the size of the object.

So, to find the size of the object

the size of image = 3 × the size of object

36 cm = 3 × the size of object

the size of object = 36/3  = 12 cm

Therefore the size of the object is 12cm.
