Answer:

181.5 in^2 to the nearest tenth.

Explanation:

This consists of a rectangle and a triangle.

Area of the rectangle = 10 * 17 = 170 in^2

Area of the triangle:

The base = 17-13 = 4 in.

The height ( that is the vertical line below the rectangle) can be found using Pythagoras:

H = √(7^2 - 4^2) = √33

Area of the triangle = 1/2 * 4 * √33 = 11.489 in^2

Area of the whole figure = 170 + 11.489 = 181.489 in^2,
