hard to say, with no figure, but I'd guess 1/2 bh = 16.275
To find the area of a triangle, you can use the formula:
Area = (base * height) / 2
Given the values:
Base = 3.5 ft
Height = 9.3 ft
Substituting these values into the formula, we get:
Area = (3.5 * 9.3) / 2
Calculating this expression, we find:
Area ≈ 16.275 ft²
Therefore, the correct answer is:
Option O 16.275 ft².
To find the area of a triangle, you can use the formula:
Area = 1/2 * base * height.
In this case, the base of the triangle is 3.5 ft and the height is 9.3 ft.
To find the area, simply multiply the base by the height and divide the result by 2:
Area = 1/2 * 3.5 ft * 9.3 ft
Calculating this gives us:
Area = 0.5 * 3.5 ft * 9.3 ft
Area = 1.75 ft * 9.3 ft
Area = 16.275 ft²
Therefore, the area of the triangle is 16.275 ft².
