Final answer:
The area of the triangle is approximately 123.75 square inches.
Step-by-step explanation:
To find the area of a triangle, you can use the formula: Area = 1/2 * base * height.
In this case, the given base (b) is 16.5 inches and the height (h) is 7.5 inches.
Substitute these values into the formula: Area = 1/2 * 16.5 * 7.5 = 123.75 square inches.
Rounded to the nearest hundredth, the area is approximately 123.75 square inches.
