A poster is shown below:
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 enlarged poster can be found by multiplying the original dimensions by the enlargement factor of 5/2.
Length of enlarged poster = (Length of original poster) * (Enlargement factor) = 12 ft * (5/2) = 30 ft
Width of enlarged poster = (Width of original poster) * (Enlargement factor) = 3 ft * (5/2) = 7.5 ft
Therefore, the dimensions of the enlarged poster are 7.5 ft by 30 ft.
