It's a trapeziod where the height is 13.8 in. and there is two lengths 8in. And 18 in.

what is the area?

To find the area of a trapezoid, you can use the formula:

Area = (base1 + base2) × height / 2

In this case, the height is given as 13.8 inches, and the lengths of the two bases are given as 8 inches and 18 inches.

Plugging the values into the formula, we get:

Area = (8 + 18) × 13.8 / 2

Simplifying that, we have:

Area = 26 × 13.8 / 2

Now, we can calculate the area:

Area = 358.8 / 2

Area = 179.4 square inches

So, the area of the trapezoid is 179.4 square inches.
