Question

You want to enlarge a 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

The new dimension is 28 inches by 28 inches

Explanation:

Given

Dimension: 5 inches by 7 inches

Factor = 4

Required

Determine the new dimension

The old dimension can be represented as (5,7)

The new dimension can be calculated by multiplying the old dimension by the factor

`New\ Dimension = Factor * Old\ Dimension`

`New\ Dimension = 4* (5,7)`

`New\ Dimension = (4* 5,4* 7)`

`New\ Dimension = (20,28)`

Hence, the new dimension is 28 inches by 28 inches
