A man bought a beautiful horse and needed a paddock to keep it in. He decided on a square shaped area and used 30 poles on each side of the square. How many poles did he use?

120poles

Step-by-step explanation:

Given

Length of each poles of the paddock = 30

Since a square has 4 sides, the perimeter of the square shaped paddock is what we are to look for.

Perimeter of a square = 4L

L is the length of each side of the paddock

Perimeter = 4(30)

Perimeter of the square = 120

Hence he used 120poles for the paddock
