Find the area of each shape and add.Let's start with the first semi-circle(half-circle)
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²
three, twelve, five, and six
Answer with Step-by-step explanation:
We are given that the set of vectors
is lineraly dependent set .
We have to prove that the set 
is linearly dependent .
Linearly dependent vectors : If the vectors 
are linearly dependent therefore the linear combination
Then ,there exit a scalar which is not equal to zero .
Let 
then the vector 
will be zero and remaining other vectors are not zero.
Proof:
When 
are linearly dependent vectors therefore, linear combination of vectors of given set
By definition of linearly dependent vector
There exist a scalar which is not equal to zero.
Suppose 
then 
The linear combination of the set
When 
Therefore,the set is linearly dependent because it contain a vector which is zero.
Hence, proved .
