Answer:
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
2/12
7/12 -5/12 = 2/12
the number 2 can go into 2 once and 12 six times so you should get 1/6 as your answer
rotation and reflection
4/3
Using the formula of rise/run:
9-1 = 8
8-2 = 6
8/6 =4/3
