b) find the cost of fencing the field at a rate of Rs9 .50 perm.

please answer the correct answer . if you don't know the answer then don't answer

Answer 1

Explanation:

a)area of rectangular field = L×B

=120×75

=9000

cost of cultivating field =9000×5

=45000rupees

b)perimeter of rectangular

field=2 (l+b)

=2×(120+75)

=2×195

=390m

then cost of fencing=9.50×390

=3705rupees

Answer 2

Answer:

Lenght=120m

Breadth=75m

find area=length ×breadth

=120×75

=9000 sq.m

(a)Cost of one sq.m=RS 5

Cost of 9000 sq.m=9000×cost of one sq.m

=9000×5

=RS 45,000

(b) Length=120m

Breadth=75m

find perimeter=2(120+75)

=240+150

=390m

Cost of one meter=RS 9.50

Cost of 390m=390m×cost of one meter

=390×9.50

=RS 3,705
