Let
x-----------> t<span>he first side
</span>y-----------> the second side
z----------> the third side
we know that
x+y+z=747------> equation 1
x=y-45------> equation 2
z=2x-----> equation 3
substitute 3 in 1
x+y+[2x]=747-------> 3x+y=747--------> equation 4
resolve the system of equation 2 and equation 4
x=y-45
3x+y=747
using a graph tool
see the attached figure
the solution is
x=175.5 m
y=220.5 m
z=2x-----> z=2*175.5------> z=351 m
the answer isx=175.5 my=220.5 mz=351 m

<u>Therefore:</u>
<u>Matrix:</u> A matrix is a rectangular arrangement of numbers in the form of horizontal and vertical lines.
Horizontal lines are called rows and vertical lines are called columns.
<u>Order of Matrix:</u> A matrix containing x rows and y column has order x × y and it has xy elements.
<u>Different types of matrices:</u>
Row Matrix: This type of matrices have only 1 row. <u>Example:</u>
<u>Column Matrix:</u> This type of matrices have only 1 column. Example:
<u>Square Matrix:</u> In this type of matrix, number of rows and columns are equal. Example:
<u>Zero Matrix:</u> It is a matrix with all elements present is zero. Example:
<u>Identity Matrix:</u> In this type of matrix, diagonal element is 1 and remaining elements are zero. An Identity matrix is always a square matrix. Example:
Answer: -0.7
