C. 24 less then double x
.

For this type of question you might want to give a domain in a set statement

ie.24 is less than 2(13,14,15,...)

Or

If my first answer was a deviation then you were probably being asked to subtract 24 from 2times a given number being represented by the variable x

the answer to this question is yes

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
