A square has 4 sides, the total interior angels sum to 360 degrees.
A pentagon has 5 sides, the total interior angels sum to 540 degrees.
Do you see a trend?
The (s) sum of interior angles equals the (n) number of sides, minus 2, times 180.
This is written as
s = (n - 2) * 180
If we put in 900 for s, we get
900 = (n - 2) * 180
5 = n - 2
n = 7
A polygon with 7 sides is called a Heptagon.

He earns $300 a week
The sales for one week are $2500
Percentage of commission on sale above $1000= 15%
[2500-1000]*(15/100)
=1500*(15/100)
=15*15 dollars
=$225
Then Gross pay of Edgar Anderson for the week = (300+225)dollars
=$525
