Answer:
280 feet squared
Step-by-step explanation:
split pic into rectangle and triangle
The bottom rectangle is 10 by 20 feet, so it has a total area of 200 feet.
The triangle has a height of 18-10 which is 8 feet. the width is 20 feet. this means we multiply 8 by 20, 160. then divide by 2 because it is half a rectanlge, which is 80 feet.
80 plus 200 feet is 280 feet.
