his field at Rs.15 per sq. meter.
(i) Find the perimeter of the field.
(ii) Find the area of the field.
(iii) Find the cost of fencing the field at the given cost.

Answer 1

Answer: Length of Field=80cm

Width of the Field=35m

Area of the field=Length * Breadth

=80 *35

=2800m²

Total cost = 2800 * 15

                = Rs. 42000

                                               

Answer 2

Answer:

Area=lxb

55x80=440sq.m

cost of fencing=440x15=6600rupees

perimeter of rectangle=(80+55)X2

=270m
