Answer:
The fence is 13 yards long.
Step-by-step explanation:
Area of square = [tex]Side^2[/tex]
Let x be the side of square playground
Area of square playground = [tex]x^2[/tex]
A square playground has an area of 169 square yards.
So, [tex]x^2=169[/tex]
[tex]x=\sqrt{169}[/tex]
[tex]x=13[/tex]
There is a fence along one side of the playground.
So, Length of fence along one side = Length of side = 13 yards
Hence The fence is 13 yards long.
