Answer:
10 yards
Step-by-step explanation:
Perimeter of a square is given by
[tex]P=4l[/tex], L is the length of each side
From the the question, the perimeter,P of the square is 40 yards.
so by substitution we obtain,
[tex]4l = 40[/tex]
Dividing through by 4
[tex] \frac{4l}{4} = \frac{40}{4} [/tex]
[tex] \implies l = 10[/tex]
