Question

the cost of cultivating a rectangular field at rate of 35 per square metre is 14000.if width of field is 4 m. find length and also find cost of fencing the field at 50 per metre​

Answer 1

Answer:

100 m, Rs. 10400

Step-by-step explanation:

Cost per sq.m = Rs. 35

Total cost = Rs. 14000

Thus, area = 14000/35 = 400 sq.m

Breadth = 4 m

Thus, Length = 400/4 = 100 m

Now, Perimeter = 2(100+4) = 2(104) = 208 m

Cost of fencing per meter = Rs. 50

Thus, total cost = Rs. 50*208 = Rs. 10400

Answer 2

100m, RS. 14000

cost per m²=RS/-35

total cost =45000

: .area=14000÷35

=400 sq.m

Breadth =4m

: . length =400÷4

=100m

Perimeter =2(100+4)

=2×104

=208

cost of fencing per meter =RS=50

: .total cost =50×208

=104000 RS/-
