To find the area of the polygon, we first need to find the area of the rectangle formed by the dimensions 15 and 7.
Area of rectangle = length x width
Area of rectangle = 15 x 7
Area of rectangle = 105 square units
Next, we need to find the area of the triangle formed by the dimensions 7 and 13.
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 7 x 13
Area of triangle = 1/2 x 91
Area of triangle = 45.5 square units
Finally, we add the areas of the rectangle and triangle to find the total area of the polygon.
Total area of the polygon = area of rectangle + area of triangle
Total area of the polygon = 105 + 45.5
Total area of the polygon = 150.5 square units
Therefore, the area of the polygon in square units is 150.5.

My apologies for the error. Let's correct it.
Since the shape resembles the letter "L", we can calculate the area by treating it as two separate shapes - a rectangle and a right triangle.
First, calculate the area of the rectangle:
Area = Length x Width
Area = 15 x 7
Area = 105 square units
Next, calculate the area of the right triangle:
Area = 0.5 x Base x Height
Area = 0.5 x 7 x 13
Area = 45.5 square units
Finally, add the areas of the rectangle and the triangle to find the total area of the polygon:
Total Area = Area of Rectangle + Area of Triangle
Total Area = 105 + 45.5
Total Area = 150.5 square units
Therefore, the correct area of the polygon is 150.5 square units.
