Question

You want to enlarge the picture by a factor of 4 from its current size of 5 inches by 7 inches what is the size of the enlarged picture

Answer 1

20 inches by 28 inches

Explanation:

The current size of the picture is 5 inches by 7 inches

If we want to enlarge the picture by a factor of 4, the perimeter will also increase by the factor of 4.

New dimension = 4(old dimensions)

= 4(5 inches by 7 inches)

= 20 inches by 28 inches

Hence, the size of the enlarged picture is 20 inches by 28 inches.
