To find the area of the first figure, which is a square, we can use the formula for the area of a square: A = s^2, where s is the length of a side.

In this case, the length of a side is 9, so the area of the square is A = 9^2 = 81.

To find the area of the second figure, which is a triangle, we can use the formula for the area of a triangle: A = (1/2)bh, where b is the base and h is the height.

In this case, the base is 13 and the height is 9, so the area of the triangle is A = (1/2)(13)(9) = 58.5.

Since the two figures are joined together, we can add their areas to find the total area: 81 + 58.5 = 139.5.

Therefore, the answer is not 99, but 139.5.
