Explain how to find the area of a trapezoid with height 4.2 m and bases of 6.3 m and 8.1 m. Give the area in your answer.

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.
