Answer:

3973.82

Explanation:

to understand this

you need to know about:

  • geometry
  • PEMDAS

let's solve:

  • there are a rectangle and a full circle

according to the question

the area of full shape

=
\text{area of the rectangle+the area of the full circle}

=(100×31.8)+(π×(31.8/2)²)

=3180+(3.14×(15.9)²

=3180+(3.14×252.81)

=3180+793.8234

=3973.8234

=3973.82

Answer and Step-by-step explanation:

So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.

Now, the semicircles. They together form a circle.

So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852

Now we add them together.

99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)

The rectangle area is 3180.

The Semi circles' combined area is 99.85.

The total area of the figure is 3279.85.

I hope this helps! Have a great day!
