We can do several rectangles and 2 triangles the easiest way is to find the area of the big rectangle minus the cut off pices
a. 1 big rectangle-2 corner triangles b. area rectangle=lenght times height=24 times 11=264 square feet the triangles bottom left one is height 11-7=4 and base 24-14=10 bottom left=1/2 times 4 times 10=20 top right is 24-20 by 11-6 or 4 by 5, area=1/2 times 4 times 5=10
so rectangle-triangles=264-(20+10)=264-30=234 square feet
It would be much easier if you attached a table. Anyway I know what you need to do. Just make an equation and put the numbers from the table given you in the task. And you'll solve it.
