John and Leslie start at the same point. John walks 3 feet north and while Leslie walks 4 feet west. If a straight line were to be drawn between John and Leslie. How long long would the line be?
This can be solved using the pythagorean theorem which means a squared + b squared = c squared so 3 squared is 9 and 4 squared is 16 which means c is 25 and the square root of 25 is 5
