Answer:
The average yearly growth o
Explanation:
Given that the tree grew from 18 ft 35 1/2 feet in 3 1/2 years.
The growth within these years is:
35 1/2 - 18
= 35.5 - 18
= 17.5
Now, this averages:
17.5/3.5 (3.5 is the number of years)
= 5
The average is 5 ft per year
 
        
             
        
        
        
Find the length of each side 240÷12=20    20 is the other length. 
12•$18=$216   for the street side and 20+20+12=52  is the total length of the other sides 52•$15=$780  is the total cost of other 3 sides  780+216=996
the total cost is $996. Hope this helped
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
The area of the rectangle is 15*5= 75 inches
The area of the 2 semicircles combined, which make a circle, are:
π*r², where r is 5
r²=25
π*25=78.53981633
75 + 78.53981633 is about 154
