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
Solution:
-6 - (-2) = -6 + 2 = -4
The first question x+y=55
The second question (1/3)x+(1/5)y=13
The third question 25
28-14= 14, that is the girls that went swimming 14-5=9, that is subtracting the 5 girls that did both. 9-4=5, that is subtracting the girls that did neither. So 5 is your answer
