the p/a ratio is the sum of the perimeter divided by the area therefore if perimeter is 20m and the area 25m2 the sum is 20/25=0.8
3600
The angle sum of a polygon is always 360 degrees. If all angles are equal, then each angle is 18 degrees. Simply divide 360 by 20.

The average of a set of numbers is the sum of all the numbers, divided the amount of numbers in the sequence. For example, the average of 12, 14, 13, 15, and 20, would be the sum of the numbers, 74, divided by the amount of numbers in the sequence, 5. So the average is 74/5, which is 14.8.
20.
2.5
The product of 20 and 5 is 100. So when divided by the sum of 20 and 5, which is 25, it is 4. The problem is very simple. 100/25=4.

20 . 2+0 = 2 20 divided by 2 makes 10. Is the same for 30,40,50,60,70,80 and 90.
In any division sum, such as 5 / 20, the second number is called the divisor.
The sum of 20 and -4 is +16, while the product of 4 and -2 is -8. The answer to the question is therefore -2.
600/50 = 12
The answer is 10. 16+4=20 20/2=10.
Yes, average is the sum of elements divided by the number of elements Exp:- x1=10, x2=20, x3=30, x4=10. then the average is 10+20+30+10 ------------------ 4 => 17.5 Average = sum of total of element ---------------------------------- no. of elements
