Area of the triangle = 12 square feet
Step-by-step explanation:
Area of a triangle is calculated by the formula,
Area = ![\frac{1}{2}(\text{Base})(\text{Height})](/tpl/images/0724/1583/7363f.png)
From the picture attached,
Height of the given triangle = Vertical distance of the top vertex = 4 feet
Base of the triangle = 6 feet
Area of this triangle = ![\frac{1}{2}(6)(4)](/tpl/images/0724/1583/4c5f5.png)
                 = 12 square feet
Therefore, area of the given triangle will be 12 square feet.
