A rectangle is shown. The length of the rectangle is labeled 12 feet. The width of the rectangle is labeled 3 feet.
What are the dimensions if the poster is enlarged by a factor of five over two ?
7.5 ft by 30 ft
15 ft by 60 ft
1.5 ft by 6 ft
15 ft by 6 ft
The dimensions of the rectangle, when enlarged by a factor of five over two, can be found by multiplying the original dimensions by this factor.
Multiplying 12 ft by (5/2) gives 30 ft and multiplying 3 ft by (5/2) gives 7.5 ft.
Therefore, the dimensions of the rectangle when enlarged by a factor of five over two are 7.5 ft by 30 ft.
