Answer 1

Answer:

you

Step-by-step explanation:

Given :

The length of a rectangular field is 140 m.

The ratio of the length to the breadth of the field is 5:3 .

To Find :

Breadth of the Field .

Solution :

\longmapsto\tt{Let\:length\:of\:the\:field\:be=5x}⟼Letlengthofthefieldbe=5x

\longmapsto\tt{Let\:breadth\:of\:the\:field\:be=3x}⟼Letbreadthofthefieldbe=3x

As Given that Length of the field is 140 m . So ,

\longmapsto\tt{5x=140}⟼5x=140

\longmapsto\tt{x=\cancel\dfrac{140}{5}}⟼x=

5

140

\longmapsto\tt{x=28}⟼x=28

Value of x is 28 .

Therefore :

\longmapsto\tt{Breadth\:of\:Rectangle=3(28)}⟼BreadthofRectangle=3(28)

\longmapsto\tt{84\:m}⟼84m

______________________

Area of Rectangle = length * breadth

Perimeter of Rectangle = 2(l+b)

Area of Sqaure = Side * Side

Perimeter of Sqaure = 4 * Side

Area of Triangle = 1/2 * base * height

Answer 2

Step-by-step explanation:

1. a matrix having non-zero elements only in the diagonal running from the upper left to the lower right.
3. The scalar matrix is a square matrix in which all the off-diagonal elements are zero and all the on-diagonal elements are equal.
4. a square matrix in which all the elements of the principal diagonal are ones and all other elements are zeros.
