A trapezoid has a height of 10 feet, and base measurements of 20 feet and 8 feet. What is the area? square feet Hint: The formula for the area of a trapezoid is: $\frac{1}{2} h\left(B_{1}+B_{2}\right)$ Enter

Step 1 ：Given a trapezoid with a height of 10 feet, and base measurements of 20 feet and 8 feet.

Step 2 ：We need to find the area of the trapezoid.

Step 3 ：The formula for the area of a trapezoid is \(\frac{1}{2} h\left(B_{1}+B_{2}\right)\) where h is the height of the trapezoid and \(B_{1}\) and \(B_{2}\) are the lengths of the bases.

Step 4 ：Substitute the given values into the formula: \(\frac{1}{2} * 10\left(20+8\right)\)

Step 5 ：Simplify the expression to get the area.

Step 6 ：Final Answer: The area of the trapezoid is \(\boxed{140}\) square feet.
