Question

A photo that is 3 inches wide by 5 inches long is being enlarged so that it is 13 inches long. How wide will the enlarged photo be?

Answer 1

Answer:

The width of the enlarged photo will be 7.8 inches

Step-by-step explanation:

Enlarging a shape is the process of increasing its dimension by a factor. That is each of its dimension will be multiplied by a number.

Given that, the original photo is 3 inches wide and 5 inches long. Also the enlarged photo is 13 inches long.

This implies the length is increased by a factor $\dfrac{13}{5} =2.6$ .

So, the width of the enlarged photo is,

$3\times \dfrac{13}{5}= \dfrac{39}{5}=7.8 \ inches$
