Hey!
------------------------------------------------
The constant of proportionality is 0.27!
We could write a word problem for this. Like:
Jared had paid $0.27 for one pencil. How much would it cost to buy 5 pencils?
0.27 x 1 = $0.27
0.27 x 2 = $0.54
0.27 x 3 = $0.81
0.27 x 4 = $1.08
0.27 x 5 = $1.35
We can see that if Jared bought 5 pencils for $1.35. Since the proportionality is 0.27 just multiply how many times you need to.
We could also write this as:

Hope This Helped! Good Luck!
Answer:
135 units²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
To calculate h use Pythagoras' identity on the right triangle on the left
h² + 8² = 17²
h² + 64 = 289 ( subtract 64 from both sides )
h² = 225 ( take the square root of both sides )
h = = 15 , thus
A = 9 × 15 = 135 units²
