Finding the extreme point :

Now,
f''( x ) at x = 1/3 and -1 is :

Therefore, it is maximum at x = -1 and minimum at x = 1/3 .
Hence, this is the required solution.
Step-by-step explanation:

First:
Break the shape into parts, this shape can be broken into 3 parts.
Next :
Put the equation for each shape
Shape 1 ( left shape)
L x h
5.4 in x 4.8 in = 25.95 in
Shape 2 (middle shape)
L x H
5in x 4.8in = 24in
Shape 3 ( right shape)
L x H
7.9 in x 4.8 in = 37.92 in
Last:
Add them all up
25.95 in
+ 24in
37.92in
——————
87.87in
Answer
87.87 in 2
I hope this helped and that I was right, have a nice day.
C = 48
c = 2a - 4
48 = 2a - 4
48 + 4 = 2a
52 = 2a
52/2 = a
26 = a <==
