Answer 2

The dimensions of the original picture is 3 inches by 5 inches .

Explanation:

Let the length of original picture be x

Let the breadth of original picture be y

A scale drawing is made to enlarge a picture by using a scale factor of 3.

So, Length of enlarged picture = 3x

So, breadth of enlarged picture = 3y

Now we are given that . The enlarged picture is 9 inches by 15 inches.

So,
`3x = 9` and
`3y=15`

`x = (9)/(3)` and
`y=(15)/(3)`

`x = 3` and
`y=5`

Hence the dimensions of the original picture is 3 inches by 5 inches .
