We could write the 5/4 various ways but I think the reduced improper fraction is simplest.
Answer: I think its B..
Step-by-step explanation: Sorry if wrong!
Let x be width.
Length: 2x
98=2x(x)
2x^2=98
x^2=98/2
x^2=49
x= sqrt(49)
x= 7 (not -7 because distance cannot be in negatives)
Therefore, the dimensions are 7"x14"
Hope I helped :)
