.find the area of a triangle,to the nearest tenth of a square foot if its base is 4.25 feet andits altitude 6.30 feet
Area of triangle = (1/2)(base)(height)
sub in your values and evaluate.
To find the area of a triangle, you can use the formula: area = 0.5 * base * altitude.
Given that the base of the triangle is 4.25 feet and the altitude is 6.30 feet, we can plug these values into the formula:
area = 0.5 * 4.25 * 6.30
Now, let's calculate the area:
area = 0.5 * 4.25 * 6.30 = 13.3875 square feet.
To round the area to the nearest tenth, we look at the digit in the hundredth place (the second decimal place). Since the digit is 8, which is greater than or equal to 5, we can round up the previous digit. So, the area is rounded to 13.4 square feet (to the nearest tenth).
Therefore, the area of the triangle, to the nearest tenth of a square foot, is 13.4 square feet.
