Question

5.The length of a photograph is 5 in and its width is 3 in. The photograph is enlarged proportionally and its length is now 10 in. What is the width of the enlarged photograph?

Answer 1

6 inches

Explanation:

In the original photograph:

• Length = 5 in.

,

• Width =3 in.

The photograph is enlarged proportionally and:

• The new length = 10 inches.

We see that the length of the original photograph was multiplied by 2. That is:

`\begin{gathered} \text{New Length}=2*\text{ Old Length} \\ 10=2*5 \end{gathered}`

Thus, similarly, we can get the width of the enlarged photograph:

`\begin{gathered} \text{ Width of the enlarged photograph}=2*3 \\ =6\text{ inches} \end{gathered}`

The width of the enlarged photograph is 6 inches.
