a piece of land in the shape of a reguler pentagon has a perimeter of 400m.calculate one side

400 / 5 = ?

80

To calculate the length of one side of the regular pentagon, you can divide the perimeter by the number of sides.

In a regular pentagon, all sides are equal in length, so dividing the perimeter by 5 will give you the length of one side.

Let's calculate it:
Perimeter of the pentagon = 400 m
Length of one side = Perimeter ÷ Number of sides = 400 m ÷ 5 = 80 m

Therefore, the length of one side of the regular pentagon is 80 meters.
