Answer:

258 ft²

Step-by-step explanation:

This shape is represented as a rectangle with dimensions of 18ft by 21 ft and a portion of it that has been cut out.

Let's find the area of the original rectangle:

  • 18ft x 21ft
  • 378 ft²

Now let's find the area of the part cut out:

  • 12 ft x (18ft - 8ft)
  • 12 ft x 10ft
  • 120 ft²

Subtract the part cut out from the original rectangle:

  • 378 ft² - 120ft²
  • 258 ft²
