    The area of a triangle is half the base * height. So you multiply 8.2 * 5 to get 41. And when you divide that by 2, you get 20.5

    Area of a triangle is calculated by using the formula A=1/2bh

    A = 1/2 (8.2) (5)

    A=1/2 (41)

    A=20.5 or 20 1/2, whichever way you think your teacher wants it.
