Answer:
B is correct option
Step-by-step explanation:
The correct option is B:
Convert 3 1/2 inches in feet by proportion:
3 1/2 = 7/2
1/4 / 7/2 = 1/x
1/2 / 7 =1/x
1/2 *x = 7
x= 7*2
x= 14ft
Convert 5 1/2 into feet
5 1/4 = 21/4
1/4 / 21/4 = 1/y
THE DENOMINATORS WILL BE CANCELLED OUT BY EACH OTHER.
1/21 = 1/y
y = 21ft
Therefore it is 14ft by 21ft, which is option B....
