Answer:
679 square feet
Step-by-step explanation:
First, I divided the shape into TWO parts, the triangle and the square. I did the triangle first. What I do is Make a quadrilateral from the triangle and solve the are for that then divide by two. So,
10*20=200
200/2=100
The first part is 100.
Then I did all the white areas.
The door is 5*3 so,
5*3=15
The area is 15.
Then the window.
2*3=6
The area is 6.
Now for the big blue square.
30*20=600
The area of that is 600.
No, you need to add the triangle to the square.
100+600=700
And now to subtract the windows and doors (you cant paint those)
15+6=21
700-21= 679
The area the must be paitned is 679 square feet.
