What’s the answer and can somebody explain how to solve it

The area of a trapezoid is calculated using the formula: 1/2(a + b)h. The diagram shows that base number one (a) is 8.5 dm and base number two (b) is 26.5 dm. The height is 9 dm. Substitute these values into the formula.

1/2(8.5 + 26.5) * 9, add 8.5 and 26.5 inside the parentheses.

1/2(35) * 9, you can now solve from left to right. Multiply 1/2 and 35.

17.5 * 9, multiply to get your final answer. The area of the trapezoid is C. 157.5 dm^2.
