Answer 1

Answer:

1. a) 60m

2. b) 85.6m

3. c) 457.96m2

4. a) Field a

Step-by-step explanation:

1. A plot of total area 3600 sq.m

so, 60×60= 3600

so, side of field = 60m

2. A plot of square shape with side measuring 21.4m

so, 21.4×4= 85.6m

or

21.4+21.4+21.4+21.4= 85.6m

3. 21.4×21.4= 457.96m2

4. For field a,

3600×200= 720,000

For field b,

457.96×200=91,592

So, a > b (a is more cost than b)
