The answer you are looking for is 60 yards! You can use the formula x*y=z Making 40*y=2400 Do 2400/40= 60 40*60=2400 Making 60 your length of the playground! I hope this helps!
You just need three numbers that multiply to make 48. Because the volume of a rectangular prism is abh. 1 1 48 2 1 24 3 1 16 4 1 12 6 1 8 2 3 8 2 2 12 2 4 6 3 4 4 3 2 8 etc
