The length of rectangular field is 7 m less than 4 times the width. the perimeter is 136 m. find the width and length

15 m and 53 m.

Step-by-step explanation:

Let the length of the rectangular field = x m

and width = y m

From the statement "Length is 7m less than 4 times the width"

x = 4y - 7 (1)

"perimeter of the field is 136 m."

2 (x + y) = 136

x + y = 68 (2)

Now we replace the value of x from equation 1 to 2

4y - 7 + y = 68

5y - 7 = 68

5y = 68 + 7 = 75

y = 15 m

From equation (2)

x + 15 = 68

x = 68 - 15

  = 53 m

Therefore, length and width of the field are 15 m and 53 m.

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
