Question

Find the cost of fencing a rectangular field 34m long and 18m wide at 2 50 per meter.what is the cost of cultivating the field at rs 4.25 per squre meter

Answer 1

Answer:

Rs 260,  Rs 2601

Step-by-step explanation:

Given to find the cost of fencing a rectangular field 34m long and 18m wide at 2 50 per meter, also the cost of cultivating the field at rs 4.25 per squre meter

We know perimeter of a rectangle = 2(l + b)

                                                         = 2(34 + 18)

                                               perimeter = 104 m

Cost of fencing for 1 mtr = Rs 2.50

 So for 104 mtr    2.50 x 104 = Rs 260

Now we know Area of rectangle = length x breadth

                                                    = 34 x 18

                                   Area = 612 sq mtr

 So the cost of cultivating for 1 sq mtr = Rs 4.25

  Therefore for 612 sq mtr we get 612 x 4.25

                                       = Rs 2601

Answer 2

➡️Answer:
1) Cost of fencing at the rate 2.50 per meter = 260 Rs

2)Cost of fencing at the rate 250 per meter = 26000 Rs

3) Cost of cultivation at the rate 4.25 per sq-meter = 2601 Rs

➡️Solution:

To find cost of fencing :find the perimeter of the field :

Perimeter of rectangular field = 2(length+breath)

=2(34+18)

=2(52)

=104 meter

➡️cost of fencing= 104×2.50 Rs

= 260 Rs

➡️To find cost of cultivation:

area of rectangular field:

=(length×breadth)

=(34×18)

= 612 sq-m

➡️Cost of cultivation of field = 612×4.25 Rs

=2601 Rs
