12. you have been hired by a museum to make a scale drawing poster of a painting to sell at the gift shop. the painting is 65in high by 105in wide. you are asked to use a 1in = 5in scale. what will the dimensions of your poster be? (2 points)

We know that
[scale]=[poster]/[painting]
[poster]=[painting]*[scale]
scale=1/5

then

for high = 65 in (painting)
[poster]=[painting]*[scale]> [65]*[1/5]> 65/5> 13 in

for wide = 105 in (painting)
[poster]=[painting]*[scale]> [105]*[1/5]> 105/5> 21 in

the answer is
The dimensions of the poster will be  15 in x 21 in

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
