Step-by-step explanation:

Total books = 368.

Sociology books = 92.

Psychology books = 3 times sociology books

= 3 x 92 = 276

Total = 276 + 92 = 368

(a) x = 4  
First, let's calculate the area of the path as a function of x. You have two paths, one of them is 8 ft long by x ft wide, the other is 16 ft long by x ft wide. Let's express that as an equation to start with. 
A = 8x + 16x
 A = 24x 
 But the two paths overlap, so the actual area covered will smaller. The area of overlap is a square that's x ft by x ft. And the above equation counts that area twice. So let's modify the equation by subtracting x^2. So:
 A = 24x - x^2 
 Now since we want to cover 80 square feet, let's set A to 80. 80 = 24x - x^2 
 Finally, let's make this into a regular quadratic equation and find the roots.
 80 = 24x - x^2
 0 = 24x - x^2 - 80
 -x^2 + 24x - 80 = 0 
 Using the quadratic formula, you can easily determine the roots to be x = 4, or x = 20. 
 Of those two possible solutions, only the x=4 value is reasonable for the desired objective. 
 (b) There were 2 possible roots, being 4 and 20. Both of those values, when substituted into the formula 24x - x^2, return a value of 80. But the idea of a path being 20 feet wide is rather silly given the constraints of the plot of land being only 8 ft by 16 ft. So the width of the path has to be less than 8 ft (the length of the smallest dimension of the plot of land). Therefore the value of 4 is the most appropriate.
