Question

the length of a rectangular field is 100 M if its perimeter is 300 metre what is its breadth answer

Answer 1

Answer:50m

Step-by-step explanation:

l = 100m

P= 300m

P = 2(l+b)

300 = 2(100+b)

300/2=100+b

150 = 100+b

b = 50m

Answer 2

perimeter= 2(l+b)
300=2(100+b)
300=200+2b
300-200=2b
100=2b
b=100/2
b=50
