    Answer:

    Base = 17.5 inches.

    Step-by-step explanation:

    Given  : A triangle has an area of 369.25 square inches. The height of the triangle is 42.2 inches.

    To find : What is the length of the base of the triangle.

    Solution : We have given

    Area of triangle = 369.25 square inches.

    Height =  42.2 inches.

    Area of triangle = \frac{1}{2}*base*height.

    Plugging the values.

    369.25 =  \frac{1}{2}*base*42.2.

    On multiplying both sides by 2

    369.25 * 2 = base * 42.2

    738.5 = base * 42.2

    On dividing both sides by 42.2

    Base = 17.5 inches.

    Therefore, Base = 17.5 inches.

    Step-by-step explanation:

    1 \div 2 \times base \times height = area

    1 \div 2 \times x \times 42.2 = \ 369.25 \

    x = 369.25 \div 21.1

     = 17.5
