  3. How do you get the area of a triangle?
    • A = b x h
    • 2

    If the height of a triangle is 4' and the base is 3' the formula would be

    • A = 4 x 3
    • 2

    • A = 12
    • 2

    A = 6

    Area is always expressed in sq. measurments
  4. How do you get the area of a trapezoid?
    • A = b1 + b2 x h
    • 2


    If the trapazoid has a bottom base of 5" and a top base of 3" and a height of 3 inches

    • A = 5 + 3 x 3
    • 2

    • A = 8 x 3
    • 2

    A = 4 x 3
