Answer 2

Answer:

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

Step-by-step 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       $3y=15$

      $x = \frac{9}{3}$                and       $y=\frac{15}{3}$

       $x = 3$                 and       $y=5$

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