Answer:
50
Step-by-step explanation:
20/28 = 3x / (4x + 2)
84x = 20(4x + 2)
84x - 80x = 40
4x = 40
x = 10
so the 2 lines are equal to 30 and 42

Answer:
The Fringe of the rug is 754 cm.
Step-by-step explanation:
Given:
radius = 120 cm
We need to find the fringe of the outside rug.
Solution:
Since the rug is in the circular form.
We can say that fringe of the outside edge of the rug can be equal to circumference of the circle.
Then we will find the Circumference of the circle.
Circumference of the circle is given 2 times 'π' times radius 'r'.
framing in equation form we get;
Circumference of the circle = ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
Circumference of the circle = ![2 \times \pi \times 120 = 753.98 \approx 754\ cm](https://tex.z-dn.net/?f=2%20%5Ctimes%20%5Cpi%20%5Ctimes%20120%20%3D%20753.98%20%5Capprox%20754%5C%20cm)
Hence the Fringe of the rug is 754 cm.
