You need to show us the circle in order to let us answer the question.
        
             
        
        
        
He will be making a right triangle with the legs being 24 x 45. The diagonal will be the hypotenuse of the triangle. To find the amount of fencing we need the perimeter of the triangle. 
Use Pythagorean theorem to find the length of the hypotenuse. 
a^2 + b^2 = c^2
24^2 + 45^2 = c^2
576 + 2025 = c^2
2601 = c^2
sqrt 2601 = c
c = 51
Adding the three lengths the total fencing needed is 
51+24+45=120 meters

Answer:

Step-by-step explanation:
The average rate of change can be found by using the following formula

Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2. 
By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5. 
Now that we know this, we can simply plug these values into the formula! 

Good luck!
