Step-by-step explanation:

7

Step-by-step explanation:

There are a few different methods of which you can solve this problem:

Method #1

Lets break this shape into 3 parts, First the large square, then the rectangle and then the triangle. First we can find the area of the square by multiplying 2 by 2 which will be 4,

Now lets work on the rectangle, Since we cut the square out of this shape, We are left with a rectangle of which the sides are 2 and 1, now you can multiply and get 2.

We are left with the triangle, This triangle has a side of 1, and 2 , which is 2, but we have to divide by 2, which is one.

Now add all of them together 4+2+1 = 7.

Method #2

You can multiply 4 by 2 then subtract the area of the triangle.

Alright, 2X4 is 8, now the are of a triangle is BH/2 lets substitute  Base = 2,

Height = 1, 2*1/2 = 2/2 = 1

8-1 = 7

If you still have any questions ask me.

Hope this helped :)

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
