The area of a triangle ( one side of the pyramid) is 1/2 x base x height.

he base is given as 0.5 foot and the height is given as 9 feet.

The area of one side is: 1/2 x 0.5 x 9 = 2.25 square feet.

There are 4 sides to the pyramid, so total area for the sides is: 2.25 x 4 = 9 square feet.

The area of the base is 0.5 x 0.5 = 0.25 square feet.

The total area = 9 + 0.25 = 9.25 square feet.
