Not sure what the measure of ____ is, can you specify?
Answer:
14 cm
All you have to do is add the four sides up and you're good to go! :)
Let's first turn all the words into numbers:
Two and four tenths = 2.4
One and six tenths = 1.6
Four and one tenth = 4.1
Now lets represent "a number" as x.
Then translate the wording into a linear equation:

Simplify and isolate the variable:

Divide by 0.8
x>1.375 or x>1 3/8
The answer is (x+5)(x-8)
Hope this helps
B. 11.0 cm, since the area of a square is x^2. 11.0 x 11.0 is 121. So that means one of the sides is 11.0
