1) Dimensions of rectangle are 14 and 7. Perimeter is:
    2*(14+7) = 42.

2)Let the number of students who chose Tiger be x.
Number of students who chose Bulldog is 4*x.
Number of students who chose Lion is 2*x.
7x = 273  -> x=273/7=39.
Answer is 2*x=78.

3) The answer is B).
A and C aren't answers because they start with positive and end with negative numbers and D isn't answer because -6 1/4 is greater than -6,53.
