<P>Answer:

i) 5:4

ii) 9:2

Step-by-step explanation;

i) length to its breadth

100:80

Then divided by 20

Length=100÷20=5

Breadth= 80÷20=4

So the length to its breadth is 5:4.

ii) First find the PERIMETER of the RECTANGULAR field

Perimeter=2L + 2B

P= (2×100)+(2×80)

P=200+160

p=360

Breadth to its perimeter

80:360

Then divided by 40

Breadth=80÷40=2

Perimeter=360÷40=9

So THEE breadth to its perimeter is 2:9.
