What is the area of Figure ABCD? A trapezoid ABCD is drawn with length of parallel sides AB and CD equal to 13 inches and 17 inches, respectively. The length of one of the non-parallel sides BC is 8 inches. Side BC is perpendicular to DC. A perpendicular line drawn from A to side CD meets CD at E.

104 square inches
120 square inches
136 square inches
168 square inches

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
