Question

Area of a rectangular field is 768 sqm and its breadth is 24 m. The cost of fencing it at Rs 20 per meter is​

Answer 1

Step-by-step explanation:

At first we have to find the length of the rectangular field

1 . Area of the rectangle is length×breadth

768=p×24

(let the length of the field =x)

2 . p = 768÷24

p =32

Length of the field = 32 m

3 . Perimeter of the rectangle = 2(l+b)

2( 32+24)

2(56)

112 m is the perimeter of the rectangle

4 . For the cost of fencing is Rs 20 per m

112×20

2240

The cost of fencing is 2240 Rs

Answer 2

Step-by-step explanation:

HEY MATE ......

$given \\ \\ area \: of \: a \: rectangular \: field = 768sq |m| \\ \\ breadth = 24 |m| \\ \\ to \: find \: length \: ...... \\ \\ solution \: \\ \\ length = \frac{area}{breadth} \\ \\ = \frac{768}{24} = 32 |m| \\ \\ so \: \\ \\ length = 32 |m| \\ \\ cost \: of \: fencing \: = 20 |m| (given). \\ \\ so \: cost \: of \: fencing \: 32 |m| = 32 \times 20 = rupees \: 640$
