Question

Find the cost of fencing a rectangular field whose length and breadth are 150m and 120m and the cost of fencing 2metro length is rupees3

Answer 1

Answer:1620rs

Step-by-step explanation:

perimeter of rectange=2(l+w)

                                     =2(150+120)

                                     =2(270)

                                     =540

hence,cost of fencing=3(540)

                                     =1620

Answer 2

⚫ANSWER⚫

Length of field = 150 cm

Breath of field = 120 cm

Perimeter of rectangle = 2 (L+B)

Perimeter = 2 (150 +120)

= 2× 270

=540m

Cost of fencing 2m = Rs.3

Cost of fencing 1m =(3÷2)

= Rs 1.5

Now cost of fencing the field

= 540 × 1.5

= Rs.810
