A baseball 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?

A.
90 square yards
B.
1,800 square yards
C.
900 square yards
D.
120 square yards

B. 1,800 square yards

To calculate the area of a square, you can use the formula A = s^2, where A is the area and s is the length of one side of the square.

In this case, the distance between home plate and first base is 30 yards. Since a baseball diamond is a square, this would be the length of one side of the square.

So, the area of the baseball diamond would be:
A = 30^2
A = 900 square yards

Since the baseball diamond has four equal sides, the total area would be 900 square yards x 4 sides = 1,800 square yards.
