An illustration shows an obtuse triangle with a base of 9 centimeters. The perpendicular height on the right is marked by a dashed line drawn from the top vertex to an extended dashed line from the base labeled as 7 centimeters. A right angle symbol is shown where the base and height meet at the dashed lines.
What is the area in square centimeters of the triangle pictured here? Express your answer as a decimal rounded to the nearest tenth. (1 point)
cm2

To find the area of the triangle, we can use the formula for the area of a triangle:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
From the information given:
Substituting these values into the formula:
\[ \text{Area} = \frac{1}{2} \times 9 \times 7 \]
Calculating the product:
\[ \text{Area} = \frac{1}{2} \times 63 = 31.5 \]
Thus, the area of the triangle is:
\[ \boxed{31.5} \text{ cm}^2 \]
