She can 18 because 40.00 divided by 2.50 is 18 :)
Answer:
Area is 582 feet squared
Step-by-step explanation:
So, it suggests you break the shape apart, which is exactly what we can do to solve this problem.
We know that the longest side is 38ft, but to find the remaining length of the top, we will subtract 21 from 38.
So: 38ft - 21ft = 17ft
Now we can break the shape. The square will be 21 by 18 ft, and the remaining rectangle shape will be 12 by 17ft.
For the area, we'll start with the square. The formula for area is length times width: A=LW
For the square, we have the length, 21, and the width 18ft. All we have to do is multiply them:
21 * 18 = 378ft. squared
Now we can move on the rectangle, which has a length of 17ft, and width of 12ft.
12 * 17 = 204ft. squared
Last step! We add our areas together to get the entire shape's area. So..
378ft. + 204ft. = 582ft. squared
Good luck :P
We gone say C hope this helps
160 i believe. to find the area of a triangle act like its a square and divide in half. for squares multiply base by height.
take the area of each shape and add it up
Here you go!
3n-4=14
+4 +4
3n=18
(Divide both sides by 3)
n=6
