Answer:An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ... ℤ is a subset of the set of all rational numbers ℚ, which in turn is a subset of the real numbers ℝ.

By what I can tell, that is telling you what the measurement of rain was per month.  For example, August had 10.  That means that in the month of August there was 10 inches of rain.
 
        
             
        
        
        
An area is when you multiply the height by the base. So, it depends on the picture and its numbers.            ---------------------
 For example:                             /        6in          /
                                             5in/                        /
                                                 /                        /        model number: 5 in×6in=30 in
                                               /                        /

Answer:
The answer I got for this equation is x=5
I hope this image helps of showing you how to solve the equation.
 
        
             
        
        
        
Because ABCD is an isosceles trapezoid, the angles A and D are congruent.
BA and CD are congruent (given) and AD is congruent to itself (reflexive property). 
Then triangles BAD and CDA form a pair of SAS triangles, so they are congruent.
BD and CA are corresponding parts in those triangles, so they are congruent (CPCTC).
