Answer:
The Dimension & Order of Matrix obtained is 5 × 3.
Step-by-step explanation:
Given: A spreadsheet.
To find: Dimension of matrix using Numbers of Spreadsheet
Dimension of Matrix is the number of rows × number of column in matrix.
It is also known as order of matrix.
Rows are horizontal and columns are vertical.
From Spreadsheet,
There are 5 rows and 3 columns
The matrix we obtain from spreadsheet is given below,
Therefore, The Dimension & Order of Matrix obtained is 5 × 3.

Answer:
b = 9.1units
Step-by-step explanation:
Find the diagram attached
Using the similarity theorem of triangle
WX/XZ = WY/WX
Substitute;
b/a+5 = 6/b
b² = 6(a+5) ... 1
Also according to pythagoras theorem on triangle WYX;
b² = 6²+a²...2
Equate 1 and 2
6(a+5) = 6²+a²
6a+30 = 36 + a²
a²-6a+36-30 = 0
a²-6a+6 = 0
a = 6±√36+4(6)/2
a = 6±√60/2
a = 6±7.745/2
a = 13.745/2
a = 6.8725
Recall that
b² = 6²+a²
b² = 36+6.8725²
b² = 83.2313
b = 9.12units
b = 9.1units
