Since a pentagon has 5 sides, you would divide the perimeter by the number of sides.

641.5/5 = 128.3cm

Therefore, the length of one side of the pentagon is 128.3cm.

Answer:

84

Step-by-step explanation:

Set up a proportion. The ratio number of gray mice corresponds (is across from) the total number of gray mice (24)

5/2 = x/24                            Cross multliply

2*x = 5*24                            Multiply 5 by 24

2x = 120                               Divide by 2

x = 120/2

x = 60 Which represents the number of white mice.

So the white mice + gray mice = 60 + 24 = 84
