1.	16. A rectangular plot of land is 50 m wide. The cost of fencing theR18 per metre is 24680. Find(1) the length of the plot.(i) the cost of leveling the plot at the rate of 7.6 per m2.
Answer» Width of the the rectangular plot = 50m Cost of fencing per metre = ₹ 18 Total cost of fencing = ₹ 4680 SOLUTION----------------- Therefore , Distance covered in fencing = => 4680/18 => 260 m Perimeter of the rectangular plot = => Length + Breadth + Length + Breadth => 2 ( Length + Breadth ) Perimeter = 260 m ( solved above ) 260 = 2 ( Lenght ( L ) + 50 ) => 260 = 2L + 100 => 2L = 260 - 100 => 2L = 160 => L = 160/2 => Lenght = 80 m ANS. The Lenght of the rectangular plot is 80 m .

Answer»

Width of the the rectangular plot = 50m

Cost of fencing per metre = ₹ 18

Total cost of fencing = ₹ 4680

SOLUTION-----------------

Therefore ,

Distance covered in fencing =

=> 4680/18

=> 260 m

Perimeter of the rectangular plot =

=> Length + Breadth + Length + Breadth

=> 2 ( Length + Breadth )

Perimeter = 260 m ( solved above )

260 = 2 ( Lenght ( L ) + 50 )

=> 260 = 2L + 100

=> 2L = 260 - 100

=> 2L = 160

=> L = 160/2

=> Lenght = 80 m

ANS. The Lenght of the rectangular plot is 80 m .
