Alright, lets get started.
Freya, a post office clerk, uses 2 yards, 1 foot, 7 inches of twine to wrap each damaged carton she repairs.
![1 inch = 0.0833 feet](https://tex.z-dn.net/?f=1%20inch%20%3D%200.0833%20feet)
So,
![7 inches = 7 * 0.0833 = 0.5833 feet](https://tex.z-dn.net/?f=7%20inches%20%3D%207%20%2A%200.0833%20%3D%200.5833%20feet)
2 yards 1 feet 7 inches means 2 yards 1 feet and 0.5833 feet
Means 2 yards
feet
2 yards 1.5833 feet
![1 feet = 0.33 yards](https://tex.z-dn.net/?f=1%20feet%20%3D%200.33%20yards)
So, ![1.5833 feet = 1.5833 * 0.33 = 0.528 yards](https://tex.z-dn.net/?f=1.5833%20feet%20%3D%201.5833%20%2A%200.33%20%3D%200.528%20yards)
Means 2 yards and 0.528 yards = 2.528 yards
It means for 1 carton, she needs twine = 2.528 yards
So, for 17 carton, she needs twine = ![2.528*17 = 42.976 yards](https://tex.z-dn.net/?f=2.528%2A17%20%3D%2042.976%20yards)
It means she needs 42.976 yards twine. : Answer

Answer:
120 cm^2.
Step-by-step explanation:
The area of one triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 1/2 * 48
= 24 cm^2
So area of the pentagon = 5 * 24
= 120 cm^2.
