The distance around a triangle, better noun as de "perimeter of a triangle"
is the total distance around the outside, which can be found by adding together the length of each side.
Perimeter (P) = Length A + Length B + Lenght C
In this case, we know that each side measure 2 \frac{1}{8}81 feet, 3 \frac{1}{2}21 feet, and 2 \frac{1}{2}21feet but we have to rewrite each one of this mixed fractions as improper fractions:
2 \frac{1}{8}81 = \frac{16 + 1}{8}816+1 = \frac{17}{8}817
3 \frac{1}{2}21 = \frac{6 + 1}{2}26+1 = \frac{7}{2}27
2 \frac{1}{2}21 = \frac{4 + 1}{2}24+1 = \frac{5}{2}25
Then we just add all of them to find the perimeter:
 = \frac{17 + 28 + 20}{8}817+28+20 = \frac{65}{8}865
A: The distance around a triangle is \frac{65}{8}865feet
Answer:
Step-by-step explanation:
Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.
Or 1260 =(n-2)x180
Dividing both sides by 180:
7=n-2
Adding both sides by 2 we have :
n=9.
Hence a nanogon will have the sum of interior angles as 1260°.
