Question

A poster is 3 feet wide and 12 feet long. What are the dimensions if the poster is enlarged by a factor of 5/2?

Answer 1

To be able to get the enlarged dimensions, we will multiply the dimension of the poster by the given scale factor 5/2.

We get,

`\text{Width = 3 ft. x }(5)/(2)\text{ = }(15)/(2)\text{ ft. or 7.5 ft.}`
`\text{Length = 12 ft. x }(5)/(2)\text{ = }(60)/(2)\text{ ft. or 30 ft.}`

Therefore, the enlarged dimension of the poster will be 7.5 ft. x 30 ft.
