    Area of a triangle=bh/2

    45=9 (?) / 2

    45=9 (10) / 2

    Therefore, h=10

    10 cm

    Step-by-step explanation:

    The area of a triangle

    A = 1/2 bh

    We know the area and the base

    45 = 1/2 * 9*h

    45 = 9/2h

    Multiply each side by 2/9 to isolate h

    45*2/9 = 2/9*9/2h

    10 = h
