The equation for this is (n-2) x 180
Replace n with the number of sides:
a. 9: (9-2) x 180 = 7 x 180 = 1,260
b. 19: (19-2) x 180 = 17 x 180 = 3,060

Answer:
20 meters long and 10 meters wide
Step-by-step explanation:
since the perimeter is 60 and one side of it is 20 then you multiply 20 by 2, 40, to get both sides. Then you subtract 40 from 60 leaving the other two sides as 20, meaning that if you divide 20 by 2 you can find that the width of the dance floor is 10 meters long.
If two fractions have the same denominator, that means the total number of parts is the same. For example, you have two batches of cookies, which each have 8 cookies.
But the numerator tells you the number of parts you are dealing with. Going back to our cookie example, say you ate 3 cookies and your little brother only had 1. If you ate 3 cookies, you ate 3/8 of the cookies. Your little brother ate 1/8 of the cookies.
So, which one is the greatest fraction? In this case, who had more cookies? That would be you. So, the greater numerator means a greater fraction.
Answer: the fraction with the greater numerator
