Sum of interior angles formula = (n-2) x 180
where n = number of sides
so,
( 19-2 ) x 180
= 17 x 180
= 3060

hope it helps :)
Lets begin with an example.
You have 100 apples. 40 % of your apples are 40. Sounds complicated?
Here is the calculation in words, number of apples times 40 percentage.
By equation: 100 * 40/100= 40. Simple huh?
% symbol represents 100.
% 15 equals 15/100; 20% is equal to 20/100 or 1/5 in a simplified way.
Have a look to question. 40 iris at last year, 15 % MORE iris this year.
What is the 15 % of 40 iris? That's the question at the end.
Recall apple example at the beginning.
40 iris * 15/100 = 6.
So, there are 6 MORE iris blooms this year. This year Savanna has totally 46 iris.
