Hello,
Please, see the attached file.
Thanks.
You must calculate how many ways can 2 people be selected from 65.
The formula is:
n! / r! * (n-r)! =
65! / 2! * 63! =
65*64*63! / 2 * 63! =
65*64 / 2 =

Answer:
false because each go up by two and I didnt even look it up
If you are saying the perimeter is 600m and the length is 22m then,
22 multiplied by 2 = 44 both side lengths
600 - 44= 556m
556m divided by 2 = 278
The width is 278m
