Separate it into two different shapes
The piece of ribbon would be 75 inches. The ribbon would be 75 inches because 1 foot would be 12 inches and you would multiply 12 by 6 to get 72. Then, 1/4 of a foot would be 3 inches because you could divide 12 and 4(the denominator you are dealing with) to get 3. Then, add 72 + 3 to get 75. Hope this helps!
There is no real shortcut in learning integration formulas. You should take time learning and understanding how the formulas are derived until you are familiar with the formulas and you can easily recall the formulas. Hope this answers the question.
<u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>
⠀
- A polygon with 10 sides ( Decagon )
⠀
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
⠀
- The value of one of the exterior angles
⠀
<u>Formula</u><u> </u><u>Used</u><u> </u><u>:</u><u>-</u>
⠀

⠀
<u>Solution</u><u> </u><u>:</u><u>-</u>
⠀
Putting the given values, we get,
⠀

Thus, the value of the exterior angles of a Decagon is 36°.
⠀

6 divided by 3 = 2
1 apple = 2 dollars
2 x 12 = 24 dollars
or...
3 apples x 4 = 12 apples
6 dollars x 4 = 24 dollars
