Hey there! I'm happy to help!
11 ft and 3 inches is 135 inches and 1 ft 8 inches is 20 inches.
To find the area of a parallelogram, you simply multiply the base by the height.
135×20=2700
We divide by 12 to see how many feet go into this.
2700/12=225
Therefore, the area of this parallelogram is 225 square feet.
Have a wonderful day! :D
