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

New_area  = 72 in^2

Step-by-step 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

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
