To find the area of a triangle, you can use the formula A = 1/2 * base * height.
In the given image, the base of the triangle is 9 centimeters and the height is 7 centimeters. Plug in these values into the formula:
A = 1/2 * 9 cm * 7 cm
A = 63/2 cm^2
A = 31.5 cm^2
Therefore, the area of the triangle pictured is 31.5 square centimeters.
Use the image to answer the question.
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.
