Question

A rectangle a photo with dimension 3 inches wide by 4 inches long is enlarged to a length of 12 inches what is the width of the enlarged print

Answer 1

9 inches wide

Explanation:

so in the text it tells you that the rectangle is 3 inches wide by 4 inches long

then it gives you the final length but you need the width. so what i did is find out how much the increase of the length was, the length was4 at the start then ended at 12 to find out how much it increased i divided 12 by 4 and got 3. that shows that the object is 3 times larger so then I multiplied the original width by 3 which would be 3*3 which equals 9. so 9 is the width of the enlarged shape.
