    A=30.24

    Step-by-step explanation:

    A=1/2h (b1 + b2)

    A = 1/2*4.2 * (6.3+8.1)

    A = 1/2x4.2 (14.4)

    A=30.24

    30.24m

    Explanation:

    To find the answer, it is important to know the the formula for finding the area of a trapezoid.

    Formula -

    A = a + b / 2 • h

    • 'A' represents the total area of the trapezoid

    • 'a' represents the first base

    • 'b' represents the second base

    • 'h' represents the height

    Now that we know the formula, substitute the variables in the formula with the values given.

    A = a + b / 2 • h

    A = 6.3 + 8.1 / 2 • 4.2

    Next, solve for 'A.'

    Step 1 - Add both bases

    A = 6.3 + 8.1 / 2 • 4.2

    A = 14.4 / 2 • 4.2

    Step 2 - Divide 14.4 by 2

    A = 14.4 / 2 • 4.2

    A = 7.2 • 4.2

    Step 3 - Multiply

    A = 7.2 • 4.2

    A = 30.24

    Therefore, the total area of a trapezoid with the height of 4.2m and bases of 6.3m and 8.1m is 30.24m.
