Answer: the area of the triangle is 150 cm².
Explanation:
To solve this problem, we need to use the formula for the area of a triangle:
Area = (1/2) x base x height
From the diagram, we can see that the base of the triangle is 20 cm and the height is 15 cm. Plugging these values into the formula, we get:
Area = (1/2) x 20 cm x 15 cm
Area = 150 cm²
Therefore, the area of the triangle is 150 cm².
