Question

Jenna created a rectangular poster for a contest with a length of 24 inches and width of 12. If she used a scale factor 1/2 what is the area

Answer 1

New_area = 72 in^2

Explanation:

Original poster

Length = 24 inches

Width = 12 inches

Original_area = Length * Width

Original_area = (24 in)*(12 in) = 288 in^2

If we apply a scale factor of 1/2, this means that every side gets reduced by half.

This means, that the area gest reduced by a factor of 4

New_area = Original_area /4

New_area = 288 in^2/4

New_area = 72 in^2
