A local magazine sells space for ads. It charges advertisers according to the fraction of a page purchased. Advertisers purchase 1/8 and 1/16 of page 20. What fraction of the page is used for ads? (please help!!)

3/16 of page 20

Step-by-step explanation:

1/8 = 2/16

2/16 + 1/16 = 3/16

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
