To find the area of a triangle, you can use the formula:
Area = 1/2 * base * height
In this case, the base is 18 inches and the height is 7 inches. Plugging these values into the formula:
Area = 1/2 * 18 * 7
Area = 9 * 7
Area = 63 inches squared
Therefore, the area of the triangle is 63 inches squared.
