To solve this problem you must apply the proccedure shown below:
 1. When you plot the given points, you obtain a trapezoid, therefore, you must apply the formula for calculate the area of a trapezoid, which is:
 
 Where  is the larger base,
 is the larger base,  is the smaller base and
 is the smaller base and  is the height.
 is the height.
 2. The dimensions are:
 
 3. Substitute values:
 
 The answer is: 
 
        
                    
             
        
        
        
Answer:
Maximum height of the arrow is 203 feets
Step-by-step explanation:
It is given that,
The height of the arrow as a function of time t is given by :
 ..........(1)
..........(1)
t is in seconds
We need to find the maximum height of the arrow. For maximum height differentiating equation (1) wrt t as :



t = 2 seconds
Put the value of t in equation (1) as :

h(t) = 203 feet
So, the maximum height reached by the arrow is 203 feet. Hence, this is the required solution.
