Answer 1

Step-by-step explanation:

Perimeter=2×(l+b)

=1600/25=64

2×(20+b)=64

b=12

area=20×12=240

Answer 2

Answer:

1.find of the breadth,2.find it's breadth and Area

Step-by-step explanation:

l=20m,b=?,fencing wire cost=1600and per m cost =25

perimeter2(l+b) =2(20+?)=25 =40(x)=25 =x=40÷25
