Final answer:
The area of the triangular garden is calculated using the formula 1/2 x base x height, which with the given base of 12 feet and height of 8 feet, results in an area of 48 square feet.
Step-by-step explanation:
The area of Joanna's triangular vegetable garden can be found using the formula for the area of a triangle, which is 1/2 × base × height. Given that the base of the triangle is 12 feet and the height is 8 feet, we can insert those values into the formula to calculate the area.
First, write the formula for the area of a triangle:
Area = 1/2 × base × height
Next, substitute the given measurements:
Area = 1/2 × 12 ft × 8 ft
Now, perform the multiplication:
Area = 1/2 × 96 ft²
Finally, calculate the result which gives us:
Area = 48 ft²
So, the area of the triangular shaped vegetable garden is 48 square feet.
