Answer 2

Answer:

The length of each of the sides of the field is 100 m

Step-by-step explanation:

Cost of fencing 1 m = Rs. 18

So, Length of fencing for Rs.7200=\frac{7200}{18}=400 m

18

7200

=400m

Perimeter of square = 4 \times Side4×Side

So, 4 \times Side = 4004×Side=400

Side = \frac{400}{4}Side=

4

400

Side = 100 m

Hence the length of each of the sides of the field is 100 m
