Equal areas are given so shape is irrelevant

There are four containers of equal height, whose bases are a circle, a square, a rectangle and an equilateral triangle having the same area. Which one of the following statements about these containers is true?

A.Their volumes are equal.✓ Correct
B.Volume of the rectangular container is larger than that of the square container.
C.Volume of the triangular container is smaller than that of the square container.
D.Volume of the square container is larger than that of the circular container.
