What is the value of the entry represented by c41

Elenna [48]

<u>ANSWER</u>

$C_{41}=2$

<u>EXPLANATION</u>

This very simple to do.

First locate the entry in $A_{41}$ in matrix A. That is the entry in the intersection of the fourth row and first column of matrix A. This entry is $7$ .

Then multiply by the scalar which is 2 to get,

$2\times 7=14$ .

Next we locate the entry in $B_{41}$ in matrix B also. Which is $4$ . We multiply by the scalar of $-3$ to get,

$-3\times 4=-12$ .

We now add these two corresponding entries to obtain,

$14+-12=14-12=2$

The perimeter of the figure is 58 units

The area of the figure is 130 unit square

Your question is not properly formatted and the diagram required to solve the question is missing.

I've included the appropriate diagram.

To calculate the perimeter of the shape, we simply add up the side lengths of the visible parts of the figure.

Having said that, the perimeter is:

$Perimeter = 7 + 8 + 5 + 8 + 3 + 6 + 3 + 5 + 7 + 6$

$Perimeter = 58$

To calculate the area, we use a different approach.

First, we split the figure into 3, we then calculate the area of each sub-figure, and then we add up the calculated areas.

From left to right, we have:

Rectangle 1

$Length = 7\\Width = 6$

Rectangle 2

$Length = 5\\Width = 6+8 = 14$

Rectangle 3

$Length = 3\\Width = 6$

The area of a rectangle is:

$Area = Length * Width$

So, the area of the figure is:

$Area = 7 * 6 + 5 * 14 + 3 * 6$

$Area = 130$
