Abaseball diamond is a square with corners at home plate, first base, second base, and third base. the distance between home plate and first base is 30 yards. what is the area of a baseball diamond?

Well since the distance between home plate and first base is 30 yards, then that means that the distance between two bases next to each other will be 30 yards aswell. So just multiply 30 X 30 which is 900. So the area is 900 yards. Hope I helped. ;)
