Answer 1

Answer:

a) 3600 sq. m.

b) 300m.

c) Rs. 1,050

d) Rs. 59,400

Step-by-step explanation:

a) Area= Length x Breadth

= 120 x 30 = 3600 sq. m.

b) Perimeter=2(L+B)

=2(120+30)

=2 x 150 =300 m.

c) Cost of fencing= Rate per meter x Perimeter

=Rs. 3.50 x 300

=Rs. 1,050

d) Cost of ploughing= Rate per sq. m. x Area

=Rs. 16.50 x 3600

=Rs. 59,400
