Answer:
c=15
8c-48+48=9c-63+48
8c=9c-15
8c-9c=9c-15-9c
\frac{-c}{-1}=\frac{-15}{-1}
c=15
Let
x--------> the total length of the water main
we know that
the number of 20 ft pipes is x/20
and
the number of 18 ft pipes is x/18
Since they differ by 14 pipes,
we have the equation
x/18 - x/20 = 14
Solve for x (by canceling fractions)
20x - 18x = 14*18*20
x = (14*18*20)/2
x = 2,520 ft
therefore
the answer is
the total length of the water main is 2,520 ft
the total area of the figure A = 144.5 cm²

How to find the area?</h3>
First, the area of a rectangle of length L and width W is:
A = W*L
Here we have:
L = 13cm
W = 9cm
Then the area is:
A = 9cm*13cm = 117 cm²
For a triangle of height H and base B, the area is:
A = B*H/2
Here the base measures 11cm, and the height is:
H = 13cm - 8cm = 5cm
So the area of the triangle is:
A= 5cm*11cm/2 = 27.5cm²
Then the total area of the figure is:
area = 27.5cm² + 117 cm² = 144.5 cm²
