The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
Alright, lets get started.
Kendrick's Kennel has 2 spots for cats for every 7 spots for dogs.
Suppose spots for cats = 2x
So, spots for dogs will be = 7x
Total spots for cats and dogs will be = 
Total spots for cats and dogs will be = 
As per given in question, total spots for both cats and dogs are 144, so

x = 16
So, spots for cats = 
Spots for dogs =
