Let's separate this shape into three parts. A smaller rectangle at the top, and one at the bottom, and a bigger rectangle in the middle.
The smaller rectangle at the top:
The equation to find the area of a rectangle is
(a = area, l = lenght, w = width)
a = l · w
Put in the values
a = 18 · 3
a = 54
Since the smaller rectangle at the bottom has the same length and width, it has the same area.
The bigger rectangle in the middle:
a = l · w
Put in the values
a = 8 · 9
a = 72
Now add all of the areas together to get the answer!
72 + 54 + 54 = 180
The answer is 180 :)

Answer:
Step-by-step explanation:
Please find the attachment.
We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.
To find the area of community pool we will use area of pentagon formula.
, where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.
Let us find the perimeter of our given pentagon by multiplying each side length by 5.
Now let us find apothem of our pentagon by using Pythagoras theorem.
Upon substituting our given values in above formula we will get,
Therefore, the area of the pool that needs to be covered is 960.42 square feet.

Step-by-step explanation:
If two figures are said to be congruent, this implies that area of both is same and both as exactly same or copy or each other.
But from the graph, it can be stated that height of figure JKLM is 4 units whereas that of other is 6 unit.

Answer:
1
Step-by-step explanation:
-20 divided by -2 is the same as 20 divided by 2, which is 10. 11-10=1 so the answer is 1.
